I haven't read any of Rebirth because I'm trying to get a mostly complete reading of New 52.
I've been trying to do this for years, so let me tell you right now: If you don't have an insane compulsion like me to keep up with EVERYTHING, just read comics without worrying about anything.
That said, if you're looking for good New 52 comics, my favorites are (in no particular order):
Justice League by Geoff Johns
Batman by Snyder and Capullo (divisive among this wiki)
Wonder Woman by Azzarello (also divisive)
Batman and Robin
Action Comics by Morrison
All-Star Western
Swamp Thing (except for the Len Wein and Kelley Jones run, that wasn't very good)
Animal Man
Batman: The Dark Knight
The Flash
Gotham Academy
Gotham by Midnight
Green Arrow (except for the first three volumes)
Aquaman
Wow, that list ended up being looong.
