I went from a race bike - Argon18 Gallium - to an aero bike - BH G7 Disc. The BH is my daily rider, although I do switch back to the Gallium every now and again. The difference in the geometry of the bikes is noticeable. I certainly feel more up-right on the race bike as compared to the BH. That said, I don't feel faster on one bike vs. the other. I do prefer riding the BH though, which is likely because the BH is new(er) and has Di2, disc brakes, etc.
I agree with some of the other comments on the thread. All of the bikes you have linked here are drool worthy. I am sure you'll be happy with whatever you get.
