OP is great; I live in tower. Yes there are rahs, but you can ignore them, besides you'll only have a problem with rahs if you get tower cos I swearrrrrr tower must bring out the rah side in people, I never really notice too many in the other courts. However saying that, I would thoroughly recommend tower! Yeah it's social, a bit crazy but NOT as bad as what people say. When I first got here I was actually shocked at how quiet it was, the girls on my corridor don't like going out much (they're really nice though.) Anyway I'd say the good thing about OP is that even if you don't like the people on your floor/corridor that much for whatever reason it's really easy to make other friends, whereas in self-catered accom you can feel like you're stuck with your flat at times.
Also, with regards to the whole crazy thing again, if you want to get a good nights sleep tower is good for that since you're so high up you don't really hear drunk people on the streets, in the courtyard etc. I dunno about the other courts though.
I'd say the worst thing about OP is the food, but that's manly cos I'm quite keen on good food and cuisine etc (sorry to sound like a saddo), most people think it's nice; it's alright. It's kinda like school dinners, but a bit nicer. A lot of people I'm friends with actually applied to self-catered and were annoyed they got catered, but now all of them are happy to be in catered. It is good coming home from uni and having a big meal all ready to eat plus they usually do something nice on a Friday. Breakfast finishes at 9.30 though which means it can be a bit of a mission getting to it.
Sorry for the essay! If you have any more questions just ask haha.
