Fun topic and very good timing as we're about to enter the next phase of the Krakoan era. I'm still reading all the books and enjoying most of them - I think the core books (X-Men, Immortal and Red) have been consistently good/great and provide a good foundation for the X-line.
As for the rest... the Ben Percy corner of things gets a lot of flack and some criticism is certainly well deserved, but overall I've been enjoying both books lately, and with X-Force I haven't enjoyed it as much since the very beginning where the first couple of arcs blew everything else of the water.
Everything else has been frankly very average - I could leave or take Legion of X, Marauders and the recent bevvy of miniseries has been OK but mostly underwhelming.
In terms of what I'm hoping for, I've always maintained that less is more, so a smaller and more focused X-line is the way to go for me. I don't think you can maintain a consistent quality with a line of 10+ books and you always end up with a few good titles and a painfully average majority.
