I have read my big old mass of Marvel backlog, and have more or less emerged with a pull list (via Comixology) for the first time in my life.
Non-Marvel:
Sonic and Sonic Universe (they're better than you probably think, I swear!)
Walking Dead
Doom Patrol
Marvel "Holy crap I love these enough that I'm probably going to double dip for nice physical copies" tier:
Gwenpool
Power Man & Iron Fist
Old Man Logan
and kind of Doctor Strange
Marvel "I am going to keep pulling these" tier:
Squirrel Girl
Mighty Thor
Amazing Spider-man
All New Wolverine
Spider-man/Deadpool
Spider-Woman (man that first trades worth of this one was really, really good, though)
Totally Awesome Hulk
Ultimates
Hellcat
Extraordinary X-men (though this one is borderline and I may drop it in the end)
Marvel "Dropping but possibly pick back up via sale or MU" tier:
Black Panther (sorry, I can see the quality, but it just wasn't clicking right with me at all)
Mockingbird (same)
Invincible Iron Man (really just didn't like it)
Moon Girl and Devil Dinosaur (toughest cut, but just wasn't quite doing enough for me)
A-Force
"Oops, I didn't buy enough to reasonably continue until another sale or something" tier:
Web Warriors
Spider-Gwen
Ms. Marvel (damn Champions sale still leaving like 5-6 issues that weren't on sale making it all awkward and expensive to fully catch up)
and Sam Wilson Cap, though I still need to read that one
Oh, and I have all of Vision, though waiting on the last one to read that. And I finished Howard, which I really enjoyed.
Now to hope that DC actually makes it feasible to catch up on their series digitally without needing to spend a crapton right now, so I could balance this list a little better...
(I've got some stuff I'm also staying firm trade-waiting on, such as the Mignolaverse, TMNT, etc, and I'm kind of aiming to be mainly fiscally responsible on Image and just buying their stuff in sales, since those are so frequent and vast in coverage. But we'll see how that goes).
