The writers seem to be encouraged/supported in talking about how their book is different than all the other ones, and I think that is a very good and healthy thing.
Astonishing X-Men: X-Men as a street team / normal people
Cable and X-Force: X-Men as criminals/outlaws
Uncanny Avengers: X-Men as part of the establishment/integration
Uncanny X-Force: X-Men as outcasts/counter-culture
Uncanny X-Men: X-Men as rebels/villains
Wolverine & The X-Men: X-Men as a school
X-Factor: X-Men as family / X-Men as a single long-term, continuity-heavy story
X-Men Legacy: X-Men as a high-concept book for adults.
X-Treme X-Men: X-Men as adventure with little continuity
Maybe your personal view of the X-Men is more UXF/Legacy. Maybe it's more UA/WatX. The fact that it's more than likely SOME of these books and also more than likely not ALL of them is a healthy differentiation of the line.
