So far I have loved all of them, so picking ONE is really hard... It's also fairly early to say. I have really high hopes for all of them, though, as they've all been really really great so far.
So I voted for the last option. As in 'can't decide,' not 'none.'
Update: I completely glanced over the theme of "current creative teams/last couple months". That complicates things. I haven't read Larfleeze yet & the other titles are coming off of the First Lantern arc & I don't expect bang-up material so quickly post major-arc. I guess I'll go with the 2 I went with before, but with GL definitely being #1 and GLNG #2 (Kyle's adventure with the new guardians seems interesting, but not enough has happened so far).
