Well, I'd have to say I'm a fan of the European school of comics, thus I'd have to go with the likes of Asterix, Tintin, Disney characters comics (they were actually mainly produced in Italy!), and the like... also stuff like Garfield, Hägar the Horrible and so on... I'm not much of a fan of the super hero genre, one of the reasons being I wasn't really much exposed to it as a kid.
Cheers.
