Umbrella Academy - don't let the guyliner pedigree scare you, it's the bestest craziest superteam since Morrison's Doom Patrol, period full stop. You will love this series. Start with the
Apocalypse Suite TPB.
http://www.darkhorse.com/Zones/UmbrellaAcademyQueen and Country is fucking awesome, and the new "definitive" collections make it hyper-affordable
All-Star Superman by Morrison and Quitely is quite great. They also did
We3, which if you haven't read yet, for fuck's sake read
We3.
I love Morrison's
7 Soldiers of Victory so fucking much. If you want a comic with a plot that fits together like a rock-solid five-dimensional tesseract, this is the one.
I think Mike Carey's
Lucifer is significantly underrated.
Pick up anything by Yoshihiro Tatsumi.
Push-Man and Other Stories is a good starting place
http://www.amazon.com/Push-Man-Other-Stories/dp/1896597858/Speaking of manga, Urusawa's
20th Century Boys and
Pluto are both being published in English, finally. The former is an amazing apocalyptic thriller set in multiple time periods, the latter a "serious" retelling of the Astro Boy mythos. Either is well worth picking up.
Don't read anything by Millar, no matter what other people tell you. I read
Chosen yesterday based on an interesting Comixology article, and boy did it fucking suck. I asked my friend to guess how it ended and he said, "with rape?" Har.

Also featuring the dumbest, most obvious "twist" ending since M. Night Shamalayan.
Also, though technically not modern, DC published some nice collections recently of kirby's
Fourth World (4 books) and
OMAC (1 book). They fucking rule! OMAC fucking rules! Fucking OMAC fuck yeah woo!
