I switch the music off straight away..... until someone does a patch with Can or Kraftwerk on it...

the only patch where I always leave the music on is Classicos 2004 - Nessun Dorma and that Brazilian stuff, it's wicked.
The Ole patch sort of feels a bit more professional, but it is a bit too Nike-fied, and it's missing loads of stuff. The JB patch has more stuff in it, but it's missing stuff that's in the Ole one. It's the nature of WE8 patches at the moment, isn't it, no one's completed a full patch yet.
JB has all the Premiership teams with new kits, so if you're mainly into that, you'll be much happier with that one - except there's some weird oddities in the squads, and some really wrong squad numbers (Rooney, Ronaldo). There are more edited stadiums in the JB one, and some really nice adboards, but the quality of the edited stadiums is better in the Ole patch, even though there are fewer of them.
Whoever comes out with the first full-kits WE8 patch will take the lead (but they'll have to improve some of the stadiums first). Just being able to use the Evo-Web option file with all kits set to default will be such a relief.
