the title says it all, personally i love geoff johns but scott snyder is really rising with his batman and superman unchained had a great first issue but also his book from valiant "the wake" is amazing! Only one issue was released but it has me hooked.
Hard one. I like so many. I love Remender's take on Captain America. KSD is great on Captain Marvel, Brubaker's run on Captain America was stellar, Busiek, Waid, Stern, of course you have the bonafide legends, Stan Lee, Jack Kirby. I can't narrow it down to one.
Sorry if I sound like a prick but just a couple corrections:
-"Who" is your favorite writer
-The Wake is a Vertigo title
Anyway, at the moment my favorite writers are (with an example title as to why in parentheses):
Matt Fraction (Immortal Iron Fist, but anything really)
Robert Venditti (X-O Manowar)
Rick Remender (Captain America)
