An ongoing Magneto series was long overdue. It's actually a little mind-boggling that Marvel hadn't pulled the trigger on one for arguably its greatest villain character (though not perhaps its greatest villain) until recent history. Though, I've gotta say... they picked a great time to do it.
The X-Force/Spider-Man crossover "Sabotage" has a special place in my collection. I feel it is my duty to preserve it for future generations so they can see everything that was wrong with comics in the early 90's.
Nothing beats finding rare collections at a comic convention. My latest trip from my favourite shelves at Ottawa Comiccon turned up two pieces of pure gold for an X-Men superfan like me: volumes one and two of "X-Men Vignettes."
Jessica Jones is going to go down in history as the greatest thing Brian Michael Bendis ever contributed to comics. It's tempting to call her the greatest female character in the history of superhero books.
I've gone on record before about how I'm not the biggest fan in the world of the writing during the Nicieza-Harras-Lobdell (NHL) era of the X-Men. While they had their flashes of brilliance, most of their work is far too wordy, is shallow (disguised as deep) and compromises a lot of the action on-page.
