What comic books should I be reading?

I grew up reading comic books. Green Lantern was my childhood superhero (do not talk to me about the movie.) I loved the X-Men, too. Batman? Hell yes. In my late teens, I graduated into Hellblazer, Shade: The Changing Man and honestly, pretty much anything that Vertigo printed. Sadly, when university rolled around, I was too much of a broke joke to afford extras like the occasional funny book.

Of late, I've been catching up on what I missed.

I've read to the end of Hellblazer (so good!) and pick up Saga, Trees and Injection on a regular basis. But I don't know what to read next. I like dark gritty stuff—I came of age in the 1990s—and I'm not sure what to check out. As I live in an RV, even though it's a big one, I don't have space to build up a huge collection of comics, trade paperbacks or graphic novels. What ever I consume needs to make it to my eyeballs, via my iPad or Kindle.

What do y'all think I should try next? Do you have any favorite titles that I should take for a spin? If so, what do you like about them and why, based on what I've told you that I dig, would I find to love in them?

Help a fella out?
