Oxford or Cambridge for Physics?

[Shinyboots]

Hey guys, I applied to both their M.Sc. programs (part III applied maths and Mmathphys) and luckily I was accepted for both. Now, considering that they cost more or less the same, what would be the best in your opinion? I slightly prefer the courses offered in Oxford and would be happier with their organization (exams at the end of every term vs all exams at the end of the year), however I know that Cambridge has a better reputation for theoretical physics.

I am interested in particular in GR, black holes and quantum gravity. 

Thanks for your help in this big decision!
