Barca, without a shadow of a doubt. Barca are one of the teams I follow, but even I get sick of the "more than a club" bollocks that they spout, and they're by no means the fairest team on the planet, but when they're on song they are the best team to watch, and I also like the fact that it's owned by the fans.
Also, Manew are, well, Manew. Although they have fallen down the pecking order of hated clubs (thanks mainly to Chelsea), they're still by no means a club that I've any affection for.
