Downsides of Brum (imho): Evening cragging has to be a midsummer-only thing (unless you like climbing in the dark), lots of travelling to get to any climbable rock, most climbing best done as weekends away which means that if you don't like camping you will end up either miserable or skint.
Upsides of Brum (imho): Only climbing areas that aren't reasonably weekendable are in Scotland, so plenty of choice (eg if raining in Cumbria, head for Dartmoor instead, can make either by last orders with a prompt start from work), if you like camping (which I do) then you've got the perfect excuse, and once you've made the effort to get somewhere then you *will* end up getting something done no matter how bad the weather and your hangover are. Usual big-city amenities, jobs etc, two good walls actually in Brum plus various others within a short journey if you fancy a change.
Depends what you want from life, probably.
