perhaps reading too much into just two pictures, for
the bigger bike your spine has a smoother curve.
For no reason, you look better on the bigger bike.
Thinking about it, a little more stretched out, racier,
at the same time you seem to look a little scrunched
up on the smaller bike, less natural, in comparison.
For once I agree with sreten. I think you do look better on the white tape bike, slightly flatter back - it allows you to be more stretched out, and probably has a little longer top tube, or what they now call reach (horizontal distance from the top of the head tube to a plumb line to the BB). I'd also think about fit evolution - how is your fit preference likely to change, barring abnormalities. Mainly, choose the bike for which your saddle is less slammed back, that has the shallower seat tube angle. You are in a moderately aggressive position on these two bikes, and I think you will want to dig in lower as you get used to the bike. That will probably result in slowly pushing the saddle back and down a bit, with the bars moving forward as you want to get more aero, with comfort.
