I'm in almost the same situation... I was accepted to York and Oxford, for the MA and MSt in Medieval Studies, and it is so hard to choose! York is ideal for me in terms of course structure and my research interests, and the program has such a great reputation. I've heard from a few people in fact that it's better regarded than Oxford. Also, as an international student relying on loans I do have to take into account the difference in tuition (i.e., college fees) and living expenses.
But I also wonder if I will end up kicking myself for passing up the chance to go to Oxford - both for the experience, and the name value and possible career impact down the line. The prestige factor does make a difference in the UK job market - how much of a difference, I don't really know. I would also like to go on to a PhD and work in the UK afterward.
Right now I'm still waiting to hear about my college placement at Oxford - I was told I should hear back in June, but nothing yet.
Have you made a decision yet? Sorry I don't have any input to share about Leeds - I didn't apply there (York was my first choice) but I've heard nothing but good things about the program. That's brilliant that you've got a scholarship - if it were me, I think, that might tip the balance in favour of Leeds, but I know how difficult it is!
