I enjoyed The Authority quite a bit more under Warren Ellis (who I can't stand otherwise) than Mike Miller...
I'd have to pick Titans (the Wolfman/Perez stuff, not the shit they're publishing now), Legion (again, the Levitz stuff, not that Abnett/Lanning crap) and Fantastic Four (Especially the Byrne and Pacheco stuff) Pacheco's FF is currently my favorite book running (now that Starman and Hitman are dead *sniff*)
