Read the ones in bold.

20th Century Boys by Naoki Urasawa (Viz): Read it, love it... But it's not 2010-2019 (I guess they go for the english translation.
Afterlife With Archie by Robert Aguirre-Sacasa, Francesco Francavilla, and Jack Morelli (Archie). Should have read it, but Archie never was big here and I don't think I saw any of the issues here.
All-New Wolverine by Tom Taylor (Marvel): Read it, really like the series, don't think it's quite Best of 2010s though. It's a solid comicbook though with a lot of character development for Laura Kinley from Mr. Fuzzity Murder Stabbity Clone to being an individual rounded character.
Archival Quality by Ivy Noelle Weir and Christina “Steenz” Stewart (Oni)
The Art of Charlie Chan Hock Chye by Sonny Liew (Abrams)
Basquiat by Julian Voloj and Søren Mosdal (SelfMadeHero)
Batman: The Black Mirror by Scott Snyder (DC)
Batman: The Court of Owls by Scott Snyder (DC): Read, did not particularly care for it, but I'm so over Batman.
Beautiful Darkness by Fabien Vehlmann and Kerascoët (D&Q)
Becoming Unbecoming by Una (Arsenal Pulp)
The Best We Could Do by Thi Bui (Abrams)
Big Kids by Michael DeForge (D&Q)
Bitch Planet by Kelly Sue DeConnick, Valentine DeLandro, Cris Peters, Kelly Fitzpatrick, and Clayton Cowles (Image) Read the first trade, but did not care too much for it. It's not bad, just not for me.
The Black Hammer Universe by Jeff Lemire and Dean Ormston (Dark Horse): Still on my backlist.
Boxers & Saints by Gene Luen Yang and Lark Pien (First Second)
Brazen by Pénélope Bagieu (First Second)
Building Stories by Chris Ware (Pantheon)
Clyde Fans by Seth (D&Q)
Copra by Michel Fiffe (Self-published/Bergen Street/Image)
Criminal by Ed Brubaker and Sean Phillips, with Elizabeth Breitweiser (Icon/Image): One of my favourite series of the last decade (though again, it started in the 2000s). Even at its worst, it's still very very good.
Daredevil by Mark Waid, Chris Samnee, Javier Rodriguez, Matt Wilson, and Joe Caramagna (Marvel): Like it, but more for the art than the writing. Not a big Waid fan.
Daytripper by Gabriel Bá and Fábio Moon (DC/Vertigo) Read it and absolutely love it.
Dotter of Her Father’s Eyes by Mary M. Talbot and Bryan Talbot (Jonathan Cape/Dark Horse)
The Encyclopedia of Early Earth by Isabel Greenberg (Jonathan Cape/Little, Brown)
The End of the F@(U$*#+g World by Charles Forsman (Fantagraphics)
Exit Stage Left: The Snagglepuss Chronicles by Mark Russell (DC): Read it, it's good but the Flintstones was better IMHO.
Fatherland: A Family History by Nina Bunjevac (Jonathan Cape/Liveright)
The Fifth Beatle by Vivek Tiwary, Andrew Robinson and Kyle Baker (Dark Horse)
Frontier #7 by Jillian Tamaki (Youth in Decline)
Gawain’s Girlfriend and the Green Knight by Polly Guo (Webcomic)
Generous Bosom by Conor Stechshulte (Breakdown)

Goodnight Punpun by Inio Asano (Viz)
Guts by Raina Telgemeier with Braden Lamb (Scholastic)
Hark! A Vagrant by Kate Beaton (D&Q)
Hawkeye by Matt Fraction and David Aja (Marvel): Read it and love it.
Hellboy in Hell by Mike Mignola with Dave Stewart and Clem Robins (Dark Horse): Solid. Was sad that it ended and it was not really the way I wanted the story to end, but still solid.
Here by Richard McGuire (Pantheon)
Hilda & The Black Hound by Luke Pearson (NoBrow/Flying Eye Books)
Hip Hop Family Tree by Ed Piskor (Fantagraphics): Read it and love it.
The Hospital Suite by John Porcellino (D&Q)
Hot Comb by Ebony Flowers (D&Q)
House of X / Powers of X by Jonathan Hickman (Marvel): I'm a big fan of this series, but again would not put it as best of the decade. It gives a new direction to the whole X-line and it has given a lot of energy to a title that needed it, but for best of a decade I think it should work as an isolated work and this is not that: this is a setup for a lot of series.
How To Be Happy by Eleanor Davis (Fantagraphics)
How to Understand Israel in 60 Days or Less by Sarah Glidden (DC/Vertigo/D&Q)
Hyperbole and a Half by Allie Brosh (Touchstone)

The Love Bunglers by Jaime Hernandez (Fantagraphics)
Lumberjanes by various (BOOM! Studios): Fun series, really good at what it does.
The March Trilogy by Rep. John Lewis, Andrew Aydin and Nate Powell (Top Shelf): As a non-American,always interesting to read historic comics about another country. Definitely worthy of inclusion.
Mister Miracle by Tom King, Mitch Gerads, and Clayton Cowles (DC): There are things I really like about it, there are things I don't like about it. Think it's one of those, not for me.
Monstress by Marjorie Liu, Sana Takeda, and Rus Wooton (Image): Like the art more than the story, but it's perfectly aimed at its audience.
Ms. Marvel by G. Willow Wilson (Marvel): Another series that is perfectly aimed at its audience.
The Multiversity by Grant Morrison (DC)
My Favorite Thing Is Monsters by Emil Ferris (Fantagraphics)
My Friend Dahmer by Derf Backderf (Abrams)
My Hero Academia by Kohei Horikoshi, Caleb Cook, and John Hunt (VIZ): I know it's very popular, but is this just another Shonen series or is there more to it?

Silver Surfer by Dan Slott and Michael Allred (Marvel): I quite dislike Slott's writing, but Allred's art won me over.
Smile by Raina Telgemeier (Scholastic)
Southern Bastards by Jason Aaron and Jason Latour (Image): I think the first trade is perfect. Kinda disappointed with the series going forward though.
Spider-Gwen by Jason Latour and Robbi Rodriguez (Marvel)
Sunburning by Keiler Robert (Koyama)
Super Late Bloomer by Julia Kaye (Andrews McMeel)
This One Summer by Mariko Tamaki and Jillian Tamaki (First Second)
Thor by Jason Aaron (Marvel): Solid run on a longrunning title.
Through the Woods by Emily Carroll (S&S/McElderberry)

The Vision by Tom King (Marvel)
The Walking Dead #193 by Robert Kirkman and Charlie Adlard (Image)
