In my opinion,
1. Batman. The best stories, imo. Snyder is awesome, though people will disagree with me on that. Greg Capullo is one of my favorite Batman artists ever
2. Batman and Robin. Fantastic character depth and relationships. Damian! It has been doing a great job with the recent team-up issues.
3. Batwoman: Hydrology was amazing. The other two arcs weren't as good, but still amazing. Great art. Sad that the creative team is leaving
4. Nightwing: Traps and Trapezes was awesome. It slows down in the middle but has picked it up as of late.
5. Batgirl: Loved it in the beginning, and has sort of dropped. It later picks up again.
6. Detective Comics: bad in the beginning. Has been pretty good lately
7. Red Hood and the Outlaws: I read it when Scott Lobdell and Kenneth Rocafort (amazing) did it. Not fond of the new artist, which mainly why I don't like it anymore
8. The Dark Knight: just ehh...
9. Teen Titans: bad. I love Tim Drake but the designs are terrible and the storyline is just so-so
The top 5 are worth reading, the rest: not so much.
