Rankings do not fairly represent quality of students when compared internationally. Very very few people will go to UB if he/she was accepted to Harvard/MIT so very few top students in US ends up in UB. University of Country (ranked the same as UB internationally but the best in that country) gets almost all smart students from that country.
Quality of education itself is mostly irrelevant - difference is small and it's good enough pretty much everywhere now.
