Princeton or Columbia?

In short - my son graduates this year and has been blessed with an opportunity to attend the Ivy League school of his choice. He’s narrowed his final two choices down to either Princeton or Columbia. He has visited both campuses and made his list of pros and cons for each. As a parent, I’m having a tough time guiding him, as I feel that my perspective on his choice is rooted in long term impact/benefits the school will provide after he graduates rather than his actual on-campus experiences while he’s a student. We have to make a decision pretty soon, so I figured I’d bring the question to this forum.

If you could choose between the two, where are you going: Princeton or Columbia (and why)?
