I'd say Liverpool every time......Liverpool and Swansea have always been very close due to football for about 50 years.
I get on great with Scousers cos unlike most Northern types they're not miserable, boring fuckers. Always full of personality.
Strong community spirit there too.....they hate the fucking Tories and The Sun, and ran that racist grifter Yaxley-Lennon and his gang of fascists out of the city.
As far as Edinburgh goes..... @Buckster's there on his gay Harley isn't he?
