which uni is better?

depends
probably LSE overall yet who knows

"LSE for what it does, UCL for everything else" is the saying...

So you definitely prefer lse over ucl?

UCL

What does the "everything else" consist of?

Not "definitely", but if I had to choose between the two I would pick LSE (unless there's a scholarship in the way or so).

Yeah but for what reasons? I mean both have great reputation globally :/ and im just so confused

There isn't any hard-set reason; the difference is not really big. It's just that, in terms of reputation, LSE is a beast. That is not to say UCL is not, but I just believe LSE has a better reputation and I would choose it if I were between the two.

What about the quality of education? Why does student satisfaction of lse is so low ?

Student satisfaction is so volatile it isn't exactly something you should rely on.
I'm at Bristol which has been receiving crappy student satisfaction scores consistently yet I'm having the time of my life.

If you can, do visit both institutions to make sure you're making the right choice.

I am afraid I cant visit them since I am from Europe. I ve heard that students of Lse expect something different from lectures and classes. What about social life? Is just the course I have applied for is relatively new at UCL. :/ i have an offer from cass though. If i get an offer from either ucl or lse should i just withdraw my offwr from cass? I just wanna go somewhere prestigious but to be happy as a person too.

Social life is what you make of it - both unis are in central London. LSE has a reputation for being socially awkward but it has been rebutted by people who're actually there.

You don't need ti withdraw - you can simply decline it by not choosing it as either your firm or your insurance choice. Cass is still reputable though!

What do you mean socially awkward?

It is claimed that it's not very social, in short. I don't believe it personally...

Lon met. Theres no difference alk unis are the same.
