Personally, I would recommend Green Lanterns over Hal Jordan. It starts a little slow, but once it hits its stride in issue 6 or so, it never misses a beat. It's also feels like a direct continuation of Johns run, as it not only uses the two Lanterns he created, but explores concepts and characters he introduced towards the end of his run. Johns run on Green Lantern is one of my favorite comic runs of all time, and Green Lanterns fills the void those books have had since he left.
Nightwing is usually a good read, I've been reading in trade and volume 3 (Nightwing Must Die!) was especially great. If you liked the Batgirl of Burnside stuff pre Rebirth, her solo book is still in that vein, just with a different creative team. Batgirl and the Birds of Prey is a fun read that really doesn't try to be anything more than that, it's never going to blow your mind, but it's consistently entertaining to read.
is Nightwing great even if I don't care about Raptor? It's the only thing that's making me hesitate.
