There's a cast iron rule, if you can't easily get to a crag mid week after work, don't live there.
1= Sheffield Grit crags within the city boundary, great lime trad. The sport climbing is either v hard or horrible but people seem to like it. Some of the best bouldering and climbing walls anywhere. 1/3 of the city is in the Peak. Nice friendly place, relatively cheap cost of living. Great vibe, one of the biggest concentrations of climbers anywhere. 'S7, the hardest climbing postcode on earth' think that was Jerry.
1= Leeds Really great city, prob access to more quality lime, similar attributes to Sheff
3 Bangor. Mountains, sea, trad, bouldering, seaside sport, and Anglesea. Great climbing walls, easy drive to crags. Parisellas cave.
4 Lancaster Really nice city, easy peasy to South Lakes and dales. Ingleton climbing wall is a revelation after corporate chains. Longridge.
5= Toon. Great, great city, local crags, good walls and easy up the A1 to gods own county for bouldering.
5= Bristol. Great city with character, good walls, varied outdoor venues within easy reach. Easy blast to Pembroke, Devon, Penwith.
7 Derby. Not as grim as it used to be, good walls, easy access to south Peak. Worth living there just to Boulder in the Churnet Valley.

Getting difficult now, I'd say Exeter, but it's all a bit spread out. Manchester and Liverpool are great cities, but it takes longer than you'd think to get to a decent crag.
