MARVELOUS X-MEN because Magneto is in it (and) he appears to be part of the team, (and) he appears to be at least an anti-hero again.
PRISONER X because that's a great collection of X-Men (attitude!) on the cover and the concept is interesting and exciting. (Bishop is kinda like the mutant Snake Plissken, it seems. So glad Bishop is an X-Men hero again!)
