This isn't quite done yet. Hopefully I'll come back to it later tonight or tomorrow. If not, or until then, I've used smilies to display how I feel about various titles.
Marvel Comics
Amazing Spider-Man - I really don't like JMS' Spider-Man. I never did, really. Even when he wrote good, enjoyable stories about Spider-Man, those stories' theme and tone never really matched what I prefer Spider-Man to be about. That said, I could still enjoy them. Since about three issues into Sins Past, though, I've lost nearly all enjoyment of JMS' Spider-Man. Going from average arc, to laughable crossover, to shameless tie-in, it doesn't seem like the book's even about Spider-Man anymore. It's Civil War featuring Spider-Man. It's JMS' Philosophy Class featuring Spider-Man. And until that changes - despite how well JMS has handled MJ and Aunt May - I really have no interest in buying the title.
Astonishing X-Men - I loved Astonishing so much when it first was launched. Gifted is still one of my favorite X-Men arcs ever. Dangerous, while not quite as good, was still a pretty fun read. That said, I really didn't feel this third arc, Torn. The plot, I think, relied a bit too much on other, previous stories, and pacing wasn't that great. While the title was still funny, and chocked full of all of those catchy Whedon-isms, it just didn't quite have the quality of the previous arcs.
Captain America -
Civil War - I've really...loathed what Civil War has done to so many characters. I really do. Iron Man, Mr. Fantastic, Spider-Man - while they might not be acting particular out of character *looks at Darthphere for approval* have certainly all been shown at their more dark and, in some cases, pathetic moment. That said, Civil War as an actual story has been relatively enjoyable. The art's fantastic, and while the story was a bit slow in getting started (and a bit too politically preachy for my tastes...and yes, I know that sounds crazy given how I feel about the Ultimates), it's really picked up more recently, and I'm very hopeful by the end of it, we'll all be left with a truly solid superhero ensemble story.
Daredevil - As embarrassing as it is to admit, I was never really one for Bendis' Daredevil. Granted, I jumped in in the middle of his run, but - while it was good - I never seemed able to appreciate it as much as most others did. That all changed when Brubaker took over. He took Daredevil in a prison setting, and seemed to cross super heroics with prison drama, even weaving in a few seriously awesome moments throughout the tale. After which, he completely switched gears, and is now giving us a story that seems as much like an old Alfred Hitchcock movie set in European than it does a DD story. This would be the absolute last title I'd ever drop, simple as that.
Fantastic Four - Civil War hasn't been kind to many characters...and more than a few books. Fantastic Four may very well suffer the most. While it has had some sparkling moments (Say, Thing's decision to leave the country), it's also had some moments that simply reeked of filler (IE, nearly all of the Reed/Sue breakup issue), and of course, it hasn't come close to the greatness of Waid's FF run.
Friendly Neighborhood Spider-Man - I don't know how to feel about FNSM. I really don't. It's had moments (whole issues, even) where it's really fun, and really great to look at, and everything I'd want in a third Spider-Man title - light, goofy adventures, and colorful, creative characters. Unfortunately, Peter David has, at one point or another, fumbled every single arc he's written so far - not to mention turned in some utterly horrible issues. While I still like, and believe in, the premise of the book, until PAD can implement it properly, I won't be reading.
Ghost Rider - This title really surprised me. It really did. I've never been a very big GR fan, and probably will never be a very big GR fan, but the title has grabbed me with its demonic plot line, and a storytelling style that seems perfectly suited to the new Ghost Rider reader.
Irredeemable Ant-Man - I'll admit, IAM hasn't quite lived up to my sky-high expectations. I expected, I hoped, for a Marvel-version of Invincible. While it's only three issues in, Ant-Man has hardly been that. However, it has been consistently enjoyable read with awesome art that I will be honestly disappointed to see go when it's (almost definitely) canceled.
Iron Man - Civil War has (nearly) made me hate Iron Man. The Knauf brothers however did the exact opposite. While I've yet to read the CW crossover issues, Execute Program was a really fun, well written arc, that really got me hooked on the title.
Moon Knight - Moon Knight is probably one of the most...cinematic comics I've yet to read. Certainly in recent memory, it is. Houston and Finch have really crafted a dark, gritty world that is just about perfect for a guy like Moon Knight to run around in - all the while highlighting the aspects of Moon Knight that make him Moon Knight, and not Batman Jr.
Nextwave - Y'know, originally, I thought Nextwave was great. It was stupid, it was funny, and the art while not only great, complimented the writing perfectly. That said, I just don't think the concept has enough depth to really be, well, good after 6 issues or so. At least, that's when I started to lose interest. Parodies are fun - they are. But everyone knows the most important thing to comedy is timing, and well, I think Ellis and Immomen made a big mistake by not calling it quits while the jokes were still fresh, and the issues were still enjoyable.
Runaways - Runaways has been as good as ever in 2006. BKV continues to deliver everything a Runaways fan would expect from him (including death...unfortunately), and has done it in a continuously fresh and enjoyable way. I certainly hope Whedon's upcoming run can live up to what BKV has done during his 40+ issue run.
Sensational Spider-Man -
Uncanny X-Men -

...barely
Ultimates 2 - I am an unabashed Ultimates lover, and Ultimates 2, much like Runaways, has just continued what it started with issue one, and seems to be building to a fevered (and hopefully excellent) closing. Sure, the delays are unfortunate, and plenty annoying, but with some of my favorite art, and with every issue being simultaneously awesome, ridiculous, and hilarious, I can't complain about this title.
Ultimate Fantastic Four - UFF this year has been a tale of two creative teams. I loved Millar and Land's run as much as I love any comic out there, but unfortunately, since they left UFF has been beyond disappointing, and certainly below mediocre.
Ultimate Spider-Man - :\
Ultimate X-Men -
X-Factor - I love this title. A lot. From it's engaging plot lines, to smooth art (except for that second artist...ick), to a cast of characters that all seem to be some of the quirkiest in all of comics, it hasn't let up since the series started, and shows no signs of letting up in the months (and hopefully years) to come.
Young Avengers -
:\ = average.
