Played in a few places, south east, yorkshire, etc. I think it depends on whether you are looking for the best team or standard. Certainly most of the top teams in nearly every major league would probably be as good as each other ie. the top Home Counties Premier League Side would compete with the top Kent/Yorkshire/Bradford side. Alot of the time sides in the north call "Pro's" what guys in the South would call a Minor Counties player or County 2nd XI player, so gauging strength isn't always easy. I would say that in terms of overall strength the Kent/Surrey/Home Counties Leagues must be up there. The Home Counties is a monster league comprising oxon,bucks,berks,herts, parts of surrey, hampshire, middlesex and contains roughly 50 divisions - so you have to be pretty good to play in the Premier League. Yorkshire potentially is the same size but all the best teams are split into many different leagues, bradford, airewhafe, yorkshire central, huddersfield drakes etc, so I'm not sure the depth of sides is all that good.
