"The devil made me do it"
Both the pre and post Flashpoint DCU have the strengths and weaknesses.
The sad part is that the DCnU had major potential, and it either turned out to be shitty from the start (Firestorm, Earth 2, Legion of Super-Heroes etc.) or are about to get shitty (Grant Morrison leaving the Superman line, cancelling the likes of Captain Atom which eventough I don't love as much as Galan does, is above the line's average). At least with the line beforehand, you know you were neck-deep in shittiness, but it's annoying to have your hopes up and then have them crushed, as it is now.
On the whole, though, I'd say:
Batman line is weaker than the Batman R.I.P/Batman & Robin era, but stronger than the Batman INC. one (mostly due to the ridiculous delays which killed all momentum).
The Superman line is much better, but only because Grant Morrison is on it, for the time being.
Wonder Woman is much better.
Green Lantern is basically the same, with a major event coming soon.
Flash is a bit weaker, but that's also due to the writer not having as much 'pull' as Johns did, who connected his run to the Universe-altering Flashpoint by having Professor Zoom, which was intriguing.
Aquaman is much better, obviously.
Justice League is much better (including the auxiliary titles)
Teen Titans are worse.
JSA are much worse than in the Geoff Johns era, but, well, after Johns left they were shitty, too.
Then we have Animal Man, Swamp Thing, Stormwatch, Captain Atom and more, which are welcomed new additions in the quality area.
Other characters though, like Firestorm, are just being butchered.
Overall, I'd say the new DCU is in better shape, definitely.
