Recommend some (gritty) comics

I've recently read/reread and enjoyed the following titles:

Preacher
The Walking Dead
Hellblazer
American Vampire
Punisher MAX
Fury MAX

But now a lot of the big DC & Marvel titles just feel kinda bland and silly in comparison, so I'm hoping for some suggestions in the same ballpark (antiheroes, complex characters, a bit of violence, etc.) Fire away please 🙂

Besides what's been listed

maybe Kick-Ass, Sin City.

Judge Dredd. Conan.

Ultimates 1 and 2?

Spawn. At the least the first 100 issues fit the description

Thanks for the input everyone. I'll give the titles I haven't already read a look. Totally forgot about Spawn btw 🙂 Any more suggestions?

Original Teenage Mutant Ninja Turtles.

It was, after all, directly inspired by Frank Miller's Daredevil run.
