I honestly can't say I can tell the difference between New 52 books and pre-New 52 books.
I mean, I don't read a ton of DC, but still.
Like, for all I know, that Geoff Johns Shazam book I read the other day could've taken place in the exact same universe as Morrison's Batman run.
Good stories are good stories regardless of the universe they're set in. Is it possible that it's easier to say that pre-New 52 is better because you can cherry pick the great stories from the however many decades that was going on for? And likewise, there's just a shorter amount of time from which to cherry pick from New 52 (thus leaving you with less great stories even if the average quality is the same)?
And that isn't necessarily meant to be rhetorical. I haven't read a ton of DC, and definitely haven't been reading DC close to as long as some of you guys here, so I really am not sure if that's the case or not.
