Bristol or Exeter Uni for Astro physics masters?

I might possibly have a offer from both uni's, but i think i will need a little help, if and when the time comes to pick. In the end i would like to go into research, so if anyone has any back ground knowlage or info on these uni's, that would be amazing. Also if anyone has studied at either uni's, please please please tell me how you liked it there, it would be a big help.
