God Loves Men Kills
Age of Apocalypse
Second Coming
Messiah Complex
Over all:
Inferno
Age Of Apocalypse
Mutant Massacre
The Twelve (yeah, I know most people hated it but I thought it was great. Unfortunately my liking it may devalue the rest of my opinions....but it is what it is.)
Operation Zero Tolerance
Recent: RAFOTSE (Plus the needed Mini Deadly Genesis, though minus that Banshee scene), is definitely my favorite post 2000. Messiah Complex and Necrosha (even with the way it ended for Selene) are close behind. Most of the rest of the events since 2000 have been drivel, Second Coming being the exception without being one of my favorite events.
Age of Apocalypse
Asgardian Wars
Mutant Massacre
Messiah Complex
Fall of the Mutants
Xcutioner's Song
Second Comming.
Over the years, I've kind of drifted away from X-Men (more actively since Morrisson took over. It really wasn't to my liking, and, with few exceptions here and there - Claremont's X-Treme X-Men, Whedon's Astonishing, etc... - no one has really been able to pull me baxk. Bendis might have definitly killed the horse with his O5 nonsense), but most of it's events cross-overs have always been pretty solid.

Inferno, Messiah Trilogy (Second Coming is actually my favorite, because Cable is a bad ass) and, God help me for the flame wall I know that's awaiting me but...
Avengers Vs X-Men.
AoA, AoX, Excutioners Song and The Phalanx Covenant... I liked the premise of Zero Tolerance, but it could have been carried out better. But it was a pretty grim story... could have been grimmer.

What's the perfect length for your X-Men crossover?
4 issue mini or full year run or something in between
I would say 12-16 issues. Could be 2 issues a month over 6-8 months or 4 issues a month over 3-4 months or some other variation.
