Quite a good question, Daredevil!
It's quite difficult to answer your question since we many never experienced at least score of deaf schools ourselves, of course.
But from what I gathered from others at Gally and NTID, we knew that in general there are several great schools while many schools were rather so-so (yet pretty good ones) and several awful-poor schools. (speaking of education only)
I would say it's most approximate that I could answer... probably others would agree the same here?!
But overall (ed, social, sports, etc) deaf schools offer much more than mainstream schools could offer for the deaf.
