It's hard to day but I think Kingdom is probably one that I look forward to the most. It's just so epic, so many crazy battles and lots of misdirection. They're not afraid to kill off a well liked character: starting early on people you expect to stick around don't.

I'm following ~400 series. Usually when a series updates I think "I'll read this later", but those two are among the ones that make me go "noice, new chapter!"
