Undergraduate vs. Graduate Research
You're still a high-school student and you may find that your interests change in university or later.  Mine did, at least twice.

In any case, one's graduate research is often in a quite different area than one's undergraduate research (if any).  (And then one's post PhD research may go far afield of one's thesis.)  Neither school should limit your graduate options significantly.  So go to the school you're most excited about.
