I recently picked up The Best American Comics 2019 on discount at Amazon. These three comics were each great, and are available online:
Bitumen or Bust by Joe Sacco
Uninhabitable by Jed McGowan
In Search of Water-Boiled Fish by Angie Wang
Also, Vera Brosgol's comic from the collection isn't free online, but she's posted some terrific hourly comics through the years
