I haven't liked most of the "mainstream" New 52 comics much. I've liked Batman, Batman and Robin, Batwing, Batwoman, the Flash, and Wonder Woman...and I think that's it for the mainstream superheroes (I absolutely loved All-Star Western, Swamp Thing/Animal Man, Demon Knights, and Frankenstein, but those aren't really their "big" heroes). Books like Justice League, Superman, Action Comics, Detective Comics (and most of the other Bat-family ones, such as Nightwing, Batgirl, etc.), I have actively hated quite a bit.
That said, Superman was superior to Action Comics by far (mostly because there was a "mystery" involved), but can't say I've been crazy about it...
