I don't buy that MIT and Stanford are undisputed "best" either. But they're damn good. And definitely top tier ... my point is that Waterloo and UBC are in the same ball park as the top ones.
My comment of "not buying it" was that there was no evidence (other than your opinion) to support your claim. Honestly, I would like to hear more about how you came to that conclusion.
I know the rankings are only one way to estimate (and would like to hear a better way :)
Is there a list that puts Waterloo or UBC better than Stanford or MIT? ANY LIST BY ANY MAGAZINE?
