thanks again for all your answers.. it's really helpful, since i'm so stuck! again still unanimous for york, and clearly the people that live there are definitely excellent!! i would agree that york is more known for humanities than soton. my english teacher did say exactly the same as you though, soton is going up - he seemed fairly neutral, though it could be an impartial teacher thing!
i am reticent to rely entirely on league tables - i know prestige is important, but as those times and guardian figures show, they're not always definitive. the two unis are high up on the times table for english, but not so much on the guardian one. though certainly york still comes out above.
the things that put me off york are the practical issues. it costs about £60 with a student railcard to travel home; also, the language module does scare me! i definitely won't have much money so shopping and things i would need to be pretty cheap.
one main thing that also draws me to soton is the music scene, however silly it sounds. i'm big on bands like we are scientists and the long blondes etc and i know they've both recently played there - whereas i can't find similar things at york. is there a particular popular scene at york? (i mean in the sense that some unis are sporty, etc).
thanks so much everyone! this is really helping.
