It depends, really.
I usually follow certain writers, like James Robinson, Tom Peyer, and Joe Kelly. These guys seem to be able to make almost ANYTHING interesting to me.
Otherwise, it's a toss-up. For example, I used to enjoy Jeph Loeb. But now the bastard has started this whole "Bring-Back-the-Silver-Age-Origin" on Superman. And I absolutely cannot stomach retroactive crap like this. The key to recognizing a writer's inability to use his imagination, is when he begins to retcon perfectly good writers that came before him. Needless to say, I literally ripped my copy of last month's Superman to pieces. Fuck 'em.
However, Joe Kelly's ACTION COMICS continues to be the best Superman on the market. PLEASE read issue #775 (still on the stands) if you haven't yet. Kal-El takes on an extreme 'homage' of THE AUTHORITY. And, for the first time, in MY opinion, Kelly truly explains the reason for a "Superman" in a world with a team of modern psychos like The Authority. It left me speechless, and with the definite impression of who the FIRST true hero of comics is. Salute!! 
I must say that Carlos Pacheco's latest stint of the Fantastic Four is incredible! I am really beginning to enjoy a creator that, not only, is a brilliant artist, BUT, can write fresh stories like these. If you haven't yet, give the latest FF issue a try. If you like Byrne's run, you won't be disappointed with Pacheco.
That said....HEY ROY! HEY FRANTA! HEY BSAMS! HEY GOB!
