Ok Im the odd one out apparently cause I like the second one better.
I think the second one looks more bulky in the picture cause it appears to have the adjustable tension backrest where the first one doesnt. Also, the top one looks like more of a squeeze frame with the back lower but the second looks like it can still be adjusted with the back dropped further down as well. The back rest hight is clearly different for each frame but again thats just a customization as well. I just really like the angle of the front tubes where the legs will inevitable rest against. The first one is kinda rounded and has more of a gradual angle and the second one cuts in and then is straight most of the way down. My frame is like the second one as far as the front tubes go and where the legs rest and I find that the most comfortable personally and keeps my legs situated nicely in the chair, doesnt allow the legs too far apart so that you need a leg strap but your legs stay far enough apart too resting on those tubes that you dont have to look into a spreader either.
EDIT: Looking at the pic on top, is that a custom build? I am not seeing a way in that pic of how you would adjust the seat hight at the back of the seat. If its not custom build might want to check how much you would actually have for adjustments in that chair.
