For me, this is one of the best eras to be honest. The books are cohesive with each other, the "X-slack" is really something to be appreciated. Also, they don't feel like random X-men groups in different books just for the sake of it. And Marvel has picked very good artists for the books while in other eras it seemed like we got what was available...
Sure, there are some books that are not good (Marauders, X-Force) but are some really amazing ones (Immortal X-men, X-men Red, Legion of X for me). And the line feels like it has a direction. It has problems, but I don't see many other eras with such good books like we have now.
