I'm new to DC comics (but not new to DC universe) and would like a recommendation of an awesome Justice League or Superman comic. Drawing style is important to me. I generally like the new 52 drawings like in Superman/Wonder Woman comic. That's one of the first comic I picked up and kept reading. However I didn't like how later in the story there were too many crossovers so I stopped reading it. I recently started reading Batman: Hush. I love the drawings and story. But I would love to start a JL or Superman comic. Any recommendation of your favorite?

If you like Hush then you should check more of Jim Lee's work, New 52 Justice League Vol 1 & 2 features Lee's artwork (couple issues in Vol 2 are other artists). Also check out further volumes as Ivan Reis takes over from here who is one of the best artists around in my opinion.

Lee has just finished a Superman story with Scott Snyder called Superman Unchained which is out end of December in trade, based on it's delays I feel I need to read it again in its entirety before giving it a reasonable opinion. Lee also worked again on Superman with Brian Azzarello (New 52 Wonder Woman) 'Superman For Tomorrow'

Superman titles I'd recommend All Star Superman (Grant Morrison and Frank Quitely), Birthright (Waid and Yu), and if you want good art Gary Frank does a great job on Superman Secret Origin, and Brainiac.

Justice League stories - JLA run by Grant Morrison, although Howard Porters art isn't for everyone. Identity Crisis, which is fantastic by Brad Meltzer drawn by Rags Morales. And if you like painted art then check out Alex Ross' work on Kingdom Come, written by Mark Waid, as well as Justice.

Nice! Thanks for the thorough answer. I'll be checking those titles out!
