Sluggy Freelance and Schlock Mercenary for me.
I took a look at Gaming Guardians once, too, but I don't have any special love for superheroes, so I didn't like the later parts of it, and they have tragic villain management - when they make a good, [or maybe rather "bad"?] powerful villain, this villain is either going to get killed off or pussified beyond all words. It's incredibly annoying, to be honest. It's a blatant Deus Ex Machina at times.
Though they have one great quote... it makes up for everything, IMO. [I'll paraphrase it]
"What will we tell the press?"
"We will tell nothing. The fate of Japan will be kept a secret, under penalty of death."
US military meeting, after D20 spaceship conquers Japan, fragging Godzilla, too. [he couldn't bear with anyone else devastating Tokyo]
However, if you talk about geekiness, it's hard to get geekier than it.
