Anyway OP imagine this - you are in a UK forum asking predominantly UK students or students who are well acquainted with UK universities about american universities. Some people tend to label LSE as better or more prestigious or label upenn as inferior, anonymous etc..
Well this is really contestable because for the record upenn is a great ivy league uni. Entry standards are far higher than those of LSE too, although im not implyign any relatnship between this and academic reputation/quality.
Try going into an american forum with predominantly american educated students or students well acquainted with american universities and ask them how good bristol/durham/ucl/kcl is. Its almost certain that most of them wouldnt even have heard of these universities before. for the record before I started researching on unis, I have only heard of oxbridge and lse in the UK (have no idea about bristol and durham and ucl at all) but have already heard of cornell, mit, princeton, carnegie mellon, brown, chicago, upenn, harvard, stanford and yale.
Rmb tat there are always only just these few universities that have the immutable international status, such as harvard, princeton or oxbridge. Few other unis share this sort of international standing. It would really be unfair to discount upenn just because it doesnt measure up to the international standing of Harvard princeton because in truth how many universities can?
Its like me going into american forum and ask - "is UCL any good?" and people say "never heard of them' and then I go urgghhh. When in fact UCL is an excellent uni - both you and me know that.
