It's such a general question there is very little point in even asking.
There are a TON of different variables that go into the decision and everyone is going to have a different list of priorities, even if you take admission and cost out of the equation not everyone is just gonna choose a top Ivy school. There's always location, research, specific major, size, family heritage, sports, and on, and on, and on.......
So unless you are just that curious, don't worry about what others would choose cost not being a concern.... that's kind of like asking what car would you have if cost were not an issue. That may be all fun to know and ask about, but would practically mean nothing in helping you decide where you would go.
Instead, think about what you want out of college, what sort of factors are important to you and make a list, and then get some ideas from others on which colleges fit your goal. In and of itself where you go to college will play a small role compared to what you do while there.
