Should I have gone to LSE instead of KCL for IR?

I've just finished my second year at KCL studying International Relations. I was ecstatic to get into KCL as it was my first choice with UCAS, and also as I went through Adjustment to join the IR course, but not switch universities.

However, of present, with the way people compare KCL to some other universities, I've been second-guessing whether I made the right choice. Particularly compared to LSE: whilst KCL has an excellent War Studies department with higher entry requirements for IR, LSE seems to be viewed overall as the higher-achieving institution. That apparently KCL is for "BTECs". Although, on the other hand, I didn't really consider LSE during my UCAS application, partly due to what I'd heard from alumni about its social environment.

I guess I'm now at a place where I worry if I should've chosen LSE for the somewhat better reputation for future prospects, irrespective of the course.

Am I being irrational? Did I make a bad decision?
