Well, I would advise you to pick the Official Handbook of the Marvel Universe A-Z Vol 1, given it seems to include a lot of entries on characters who need corrections, but I don't know if its content is really that good (it seems to be copy-pasts from older handbooks, from what I've heard (I haven't it, but I regularly ask Monolith616 for parts of it). That's the one I would take as it has seemingly a lot of updated post-events stuff, and of mutant stuff too.

A shame for Marvel, safe for X-Men: Earth's Mutant Heroes Vol 1 1 or Heroic Age: X-Men Vol 1 1, they haven't issued many (any?) subspecies handbooks, and it's really picking sentences in individual entries scattered here and there.
