Liverpool didn't strike a chord, individually I've met some lovely scousers, but the culture itself I find to be pretty irritating, humour-wise it's not dry enough. Harry Enfield was spot on with his scouser sketches.
What I liked about Manchester, was that I found culturally the people are very open and some excellent music has come out of there, The Fall, Joy Division, John Cooper Clarke, etc and it reminded me of London before much of it was gentrified.
Strange you focus on death metal as it's pretty niche as music goes. I was using a historical example as I don't listen to too much British music at the moment, as the situation is pretty dire, it seems to be death metal (not my thing) the most boring kind of Indie/alternative, (I like alternative but the British stuff is just boring) Grime or club crud. At the moment I'm interested in the pyschedelia, the good stuff seems to mostly be coming from the US or Australia.
