I guess the academics aspect is the most complex one, and as you guys have pointed our I'm probably the only one who can figure out what is the best fit for me. I will be questioning professors, and possibly students, about that.
At the same time, you guys can definitely help me out on the "quality of life" aspect. Which university is located in the best city/neighborhood? Which campus is more beautiful, or more comfortable? Which place has the nicest people? The most vibrant community? The most interesting cultural features? Etc.
I'm obviously biased toward UIUC, but it's limited. It's Chambana... but you do have to travel to see or do much beyond campus culture.
