I searched but did not find any discussion comparing the merits of the two major cryonics providers in the US, so I figured it might be productive to start such a discussion myself by posing the question to the community: which provider would you choose, all things being equal: Alcor or the Cryonics Institute?
From my research, Alcor comes across as the flasher, higher-end option, while CI seems more like a Mom-and-Pop operation, having only two full-time employees. Alcor also costs substantially more, with its neurosuspension option alone running ~$80k, compared with CI's whole-body preservation cost of ~$30k. While Alcor has received far more publicity than CI, much of it has been negative. The Ted Williams fiasco is probably the most prominent example, although the accuser in that case seems anything but trustworthy. However, Alcor remains something of a shadowy organization that many within the cryonics community are suspicious of. Mike Darwin, a former Alcor president, has written at length on both organizations at http://www.chronopause.com, and on the whole, at least based on what I've read, Alcor comes across looking less competent, less trustworthy, and less open than CI.
One issue in particular is funding. Even though Alcor costs much more, it has many more expenses, and Darwin and others have questioned the long term financial stability of the organization. Ralph Merkle, an Alcor board member and elder statesman of cryonics who has made significant contributions to other fields like nanotechnology, a field he practically invented, and encryption, with Merkle's Puzzles, has essentially admitted(1) that Alcor hasn't managed its money very well:
"Some Alcor members have wondered why rich Alcor members have not donated more money to Alcor. The major reason is that rich Alcor members are rich because they know how to manage money, and they know that Alcor traditionally has managed money poorly. Why give any significant amount of money to an organization that has no fiscal discipline? It will just spend it, and put itself right back into the same financial hole it’s already in.
As a case in point, consider Alcor’s efforts over the year to create an “endowment fund” to stabilize its operating budget. These efforts have always ended with Alcor spending the money on various useful activities. These range from research projects to subsidizing our existing members — raising dues and minimums is a painful thing to do, and the Board is always reluctant to do this even when the financial data is clear. While each such project is individually worthy and has merit, collectively the result has been to thwart the effort to create a lasting endowment and leave Alcor in a financially weak position."
Such an acknowledgement, though appreciated, is frankly disturbing, considering that members depend utterly on these organizations remaining operational and solvent for decades, perhaps even centuries, after they are deanimated.
Meanwhile, CI carries on merrily, well under the radar, seemingly without any drama or intrigue. And Ben Best seems to have very good credentials in the cryonics community, and Eliezer, one of the most prominent public advocates of cryonics, is signed up with them. Yet the tiny size of the operation still fills me with unease concerning its prospects for long-term survivability.
So with all of that said, besides cost, what factors would lead or have led you to pick one organization over the other?

Yes, unquestionably some of the "information" that constitutes your person hood is in your gut, your glands, your immune system and your peripheral nervous system. However, your position would seem to imply that these things, and things much more central to your identity, such as your brain structure, are like unchanging books or artifacts on a museum shelf. They aren't. In fact, by the time you are 80, you will have lost roughly a third of your brain mass and your brain will be a tattered "remnant" of what it once was. You're now losing roughly 80K neurons a day. The practical consequences of this will be a massive transformation of your personality and of your functional capabilities. If that change were to be imposed on you all at once, you would not only be horrified, you likely wouldn't even recognize the resulting individual as the same person. More likely, you'd consider that individual to be a cruel and sadistic parody of yourself.
The point is that your "identity" is a dynamic thing which is badly degraded over time by aging. This is important information to keep in mind, because it provides context for what I'm going to say now. I have known a good number of people who have no stomach or intestines. They could not eat food of any kind. They stayed alive by virtue of total parenteral nutrition (TPN) which provides for all their fluid and nutritional needs intravenously. These people did not undergo any perceptible change in memory, personality or person-hood. At least three such people I've known have also had kidney transplants. That's even more interesting, because we now know that many patients with successful, long term grafts become chimeric with the donor! Donor immune and stem cells colonize the patient! Similarly, any mother is chimeric for each of her fetuses. In fact, in animals, if you injure the mother's heart or brain during pregnancy, the fetal stem cells are the ones which repair the damage - massively remodeling the damaged organs. This chimerism seems to be an evolutionary adaptation to protect the mother against injury during pregnancy.
To my knowledge, no one is upset at the idea that a significant fraction of the stem cell population in such people is ALIEN. And those stem cells are genetically and functionally different from the native ones. Maybe more than the gut, the immune system is an extension of the brain - they interact dynamically and the immune system can and does profoundly effect mood and behavior.
So what is identity? Well, that's complicated, but one thing is clear, it is NOT static and a lot of the changes in the structures which determine it happen all the time as part of life, and you have little or no control over them. Where this intersects whole body vs. neuro is that you have the need (arguably the necessity) to decide just what parts of you are truly essential to your person-hood AND at what cost in risk to survival they can be taken along during cryopreservation.
If you are smart, cool, and rational, you'll try to determine just what parts of you are really you - are really essential to your person-hood. This would be an impossible black box of a task were it not for contemporary transplant and artificial organ medicine. There are tens of thousands of people on dialysis or who get kidney transplants. There are people with no hearts, or new hearts, and people with gut, liver, pancreas and renal transplants. There are countless people with bone marrow transplants and countless others whose spinal cord and peripheral nervous system have been functionally disconnected from their brains. Do these people constitute an acceptable degree of survival for you as persons? If so, I would suggest you delve into the logistics, economics and hard practical realities of cryopreservation that must endure over a period of many decades, or far more likely, a century or two. It is NOT easy to handle, move or care for whole body patients. They are a ball and chain and cannot be moved or evacuated quickly. They are subject to a large burden of state regulation which neuros are not, and they suffer additional injury to the brain as a result of compromises necessary to achieve cryoprotection and cooling.
If you think that those components of you identity present in your body are worth those added risks, then you should go whole body. However, my question is, where is the empirical evidence to support that belief? I've known many, many transplant patients well, and neither they nor I saw any noticeable transformation in their identity. Indeed, the transformation, such as it was, was the return to fully functioning person-hood which resulted from becoming chimeric with another human being or a machine.
Thanks for the very thoughtful reply. I hadn't properly considered the "ball and chain" risks of whole body you mentioned. Is there much of a chance that technology will develop in a way so that I will be revived sooner if I go with whole body rather than neuro?
