As Jedi (or more likely his wife) said, it varies.
I'd disagree about UNC being a top 5 clinical program. I went to dental school there so I got to see it quite a bit. It's an excellent program but is heavily research-based. You'll spend a lot of time in lecture and doing research when other programs would have you in the clinics.
I'm biased but I'd say from my experience the best clinical programs are Cinci, Ohio St, and Baylor. I've heard great things all-around about san antonio, unc, iowa, fl. A lot of it has to do with your personal experiences on interviews. I absolutely loved Children's Hospital of Wisconsin (milwaukee). I like the staff, the residents, and their preventative approach to treatment. I interviewed at some NY programs and wasn't a big fan of northeast programs. They seem to have a different tx philosophy and are partial to incoming residents from NY dental programs. Harvard was cool but the clinic is very old. That, and they've prevented residents from graduating for not completing research on time. That was enough to scare me off.
