You weren't blown away by Birmingham's campus?! I think it's pretty awesome for a city university
I'd choose Birmingham personally, for the prestige factor. The legal industry is one of those industries where your university name is quite relevant.
But then again I don't study Law and am not going into the legal industry so I'll let the pro's do the talking. (I just did the unspeakable on TSR and showed my lack of credentials - take note A-level students)
