...and I'll even rank them for you
1. THUNDERBOLTS! Only comic I've collected from day one, and still collect. It's gone through a hell of a lot of changes; and each change is glorious. I've never been unhappy with this comic, and that's over 130 issues! WOW! 130 issues of AMAZINGNESS!!!
2. X-FORCE. Kyle and Yost make a dynamite pair of writers. From New X-men to this; I think their work is astonishingly good. They have a great love for their characters, and a great knowledge from which to draw other Marvel characters into their mix. Only Fabian and Kyle/Yost have ever made me cry from their writing (in a good way).
3. TIE - Dark Avengers and Dark Wolverine. Both excellent stories about very anti-heroes. Great arc, great art, great everything.
5. ASTONISHING X-MEN. Simply beautiful art; with a great team selection and Warren Ellis writes a fantastic Emma Frost. The story is provocative and the various character interactions make me smile (Armour/Beast, Emma/Storm, Wolverine/Scott, all excellent).
6. UNCANNY X-MEN. Great stories, let down by "porn" art (that I didn't notice until someone pointed it out, darn it!).
7. MS. MARVEL. This probably would be higher (above Uncanny at-least), if last issue hadn't been very disappointing.
8. TIE - Deadpool and Deadpool: Merc w. a Mouth. Mindless fun, from start to finish; and in Deadpool you can pretty much do anything and it works. Alas, never, EVER as good as Cable and Deadpool; which was probably my next favourite comic ever after Thunderbolts and New X-men.
10. AVENGERS: INITIATIVE. Just started. So far (all of one issue) I enjoyed it
Not to long ago dropped Runaways, Young Avengers, Buffy the Vampire Slayer and X-Factor. Partly I wanted to just collect 10 comics MAX, and partly they just stopped being interesting/dynamic.
