I'd probably skip Regent.
Generally, if there's a good gay population where the school is located, then it's a good place to be in terms of places to go out and that, but that doesn't necessarily translate to a good gay group on campus. Places where it's a bit more hostile to the family tend to be the places that spawn more on-campus stuff. (With, I'm sure, a few exceptions.) So, it depends on what you're looking for.
If you're considering different schools, look at their student organizations and, if they have a gay group listed, contact someone in the group and ask what it's like at the school and in the area where the school's located.
