Thanks again. It is incredibly hard to "see" yourself in new glasses so the input is very valuable. The near even breakdown in preference tells me that I can't go too far wrong with either one, which helps a lot.
I do think the nature of the photos may have skewed the comparison (in different directions for different people). I wish I was thinking about posting the photos when we took them.
I'm still not 100% decided, but leaning in one direction.
#1 is more retro and interesting, and perhaps more "academic" looking. The brown design detail and nice metal temples (neither really visible in the photo) are subtle but very cool.
#2 is more modern and bold, and to quote Angie, more "creative". They are a semi-transparent material (Angie says it looks like ice) with a black surface coating, which is a very nice effect.
Of course, both pairs have their own Seinfeld reference:
