The list is endless, visit their websites, look up all the teachers and programs they have going. Now research those and you will see how deep the rabbit hole goes.
Top university implies that these schools have a large hub of academic progress, it might not be in a tangible form but the stuff they do at those universities does make a difference.

I'm a firm believer in the malevolence of unnecessary statistics. The only point I've ever seen in college rankings is for people to gloat over people in other colleges. I can't imagine the benefit of knowing just how these colleges rank according to an arbitrary study.
Like peer review score, employer score etc. But even then, I think this is more like a voting scheme to obtain scores rather than detailed assessment of each department/ research / paper published / nobel laureates produced/ entrepreneurs produced / innovation quotient etc.
There's no point being in the crappiest department of the "best" university.
