I reject and condemn the bland, unhelpful names "System 1" and "System 2". I just heard Micheal Morris, who was a friend of Kahneman and Tversky, saying in his econtalk interview that he just calls them "Intuition" and "Reason".
To the best of my ability to recall, I never recognize which is which except by context, which makes it needlessly difficult sometimes. Personally I would go for 'subconscious' vs 'conscious' or 'associative' vs 'deliberative' (the latter pair due to how I think the subconscious works), but 'intuition' vs 'reason' makes sense too. In general, I believe far too many things are given unhelpful names.
Disagree, but I sympathise with your position.
The "System 1/2" terminology ensures that your listener understands that you are referring to a specific concept as defined by Kahneman.

"Unconscious" is more about whether you (the part that I can talk to) can see it (or remember it) or not. Sometimes slow, deliberative reasoning occurs unconsciously. You might think it doesn't, but that's just because you can't see it.
And sometimes snap judgements happen with a high degree of conscious awareness, they're still difficult to unpack, to articulate or validate, but the subject knows what happened.
