Now that you have narrowed down your undergraduate choices to a short list of institutions to attend (assuming you got at least two offers), the time has come to compare the schools you got offers from, in terms of academics and otherwise, unless you applied early decision, in which case this really is something you should do before confirming an early decision application.
One aspect that may come across as paying too much attention to the details would be to pay attention to research activity in your field(s) of interest. Of course, this is going to affect what research opportunities you will have access to internally, as well as upper-division electives and hence what you will get out of your degree. Also graduate applications are written with research fit as the centerpiece. But don’t go too deep into debt, though, since you’ll only likely feel the difference academically in the last two years of undergrad.
