It's a personal choice, but I don't find Ultegra to be ugly at all. As was posted above, it sounds like you've made up your mind already.

I have both groups (Force and Ultegra). Overall, I prefer Ultegra because IMO, the most important part of the group (the brake/shift levers) fits me better with Ultegra. That (IMO) should be the biggest part of your decision because it's a contact point on the bike. SRAM is lighter, but IMO, the levers feel kinda cheap. The Ultegra stuff is heavier and a lot of the weight is in the shifter, but I'm glad Shimano didn't cheap out there. When I grip the lever, I feel like it's gripping my back...aka pistol grip.

If you're worried about ugly, then the 11-32 cassette is your primary concern. My wife runs that on her bike and that thing looks ridiculous...like a dinner plate. Overall, it's a much simpler and more reliable setup than the 9 speed triple that she had, so the ugly is worth something.

With the camera angle on Contador's bike, it's hard to tell...but that doesn't look like an 11-32. Maybe an 11-28? I'll post a pic of the 11-32 if you want to see it.
