I would recommend either
Wolverine and the X-men and/or
Uncanny X-Force since I was a new X-Men reader and got into them easily when I could no other book before (other than Morrison's awesome run on New X-men from a decade ago). I read the latter in spurts so not up to date on it but after I believe the 2nd arc some characters from that make their way into W&tX-M.
Uncanny X-Force is a covert team of Wolverine, Deadpool, Psylocke, Fantomex, and Archangel who are tasked with basically killing the major threats rather than capturing or subduing. Doing horrible but necessary things other teams wouldn't touch. The art team rotates arc to arc, but with the same colorists it keeps things fairly consistent.
Spoilers but after seeing
this page I knew I had to read this book.
Wolverine and the X-Men has Wolverine rebuild the Xavier school and become the headmaster. The most fun comic I've read in a long while. God damn I love this book.
