Justice League Dark is a fun read.  The addition of new characters and greater emphasis on action have been positive changes.  Although, I was one of those (few?) who also enjoyed the earlier issues with slower pacing and more focus on character relationships.  The artwork was also more solid, back then.  But I have few complaints.  Honestly, I'd buy this monthly just for the awesome cover art.  I recommend it and keep coming back monthly.
Stormwatch is the DC book I'm most excited to read each month.  Every issue does something I didn't expect, and unfolds new aspects of the characters and their relationships.  There's never a dull moment, and page space is used to good effect.  I didn't think I'd like this series, and I was very skeptical of the chosen characters...but I love it.  I didn't want to see ____ leave the team, but it hasn't hurt the book one bit.  I can't get enough, and highly recommend.
Swamp Thing is what I call high value.  Art, story, every aspect is top-notch.  I dropped from my pull awhile back, because I just wasn't feeling it.  With work slowing down, I might pick this one back up along with a few other titles.  Although, I still have to read all of Alan Moore's version.  The few that I have read were exquisite.  I'll probably read up on those before coming back to the current run.
I just read the latest Frankenstein, AOS.  I love stuff like this.  I haven't touched this title in a really long time. It looks like I've missed out on some cool stuff.  Will probably buy up some back issues of this one.
