I haven’t read all of these, but they seem like reasonable picks with the possible exception of The Nib, which is a publisher more than it really is a single comic IMO. Probably the book I’d put on the list to replace it would be My Lesbian Experience With Loneliness.

Supermutant Magic Academy might also make my personal list, though that’s less “It’s one of the best comics of the decade” and more “I really like this”, if that makes sense. 

I wouldn’t argue for Homestuck as one of the “best” comics of the decade (maybe at its peak), but it was certainly important and influential. Even moreso Raina Telgemeier’s books, and her not being represented on the list at all is a little surprising. Like, yeah, I wouldn’t give Smile to a 30-something friend to read, but she’s a pretty impactful and beloved author for a reason. 

Though if we’re going down the road of picking comics that best represent comics in the 2010s, a case could be made for Bartkira. It’s a comic that simply could not have existed until this decade.
