I think Liverpool would be first over bragging rights but I can't hate the fans because they are a part of the city and I have met some nice ones.
Man City would definitely be second because I do not like their fans and it feels great beating them.
I think spurs and Aston villa are two teams that i always enjoy beating and playing against but I don't have any hatred whatsoever for them
clubs I like would be Arsenal (really being run well), blackpool (seem to have good fans), and I had a soft spot for Bolton but they are gone so meh
Edit: Also like reading because of their manager and I remember one of the first games I watched was reading v. sunderland.
