here are a few i find cool

bob and george (https://www.bobandgeorge.com/) - i don't even think i need to elaborate on this one, one of the first influential sprite comics on the internet, kinda influenced my writing when i read through it about a year ago (maybe a bit too late to do so? eh, whatever)

powerup comics! (https://www.theduckwebcomics.com/Powerup_Comics/4946728/) - parody of the two gamers on a couch trope that penny arcade and ctrl+alt+del kinda popularized (and sweet bro and hella jeff inherited, if not for a small moment) made to troll the duck website

gamer dilbert (https://www.theduckwebcomics.com/Gamer_Dilbert/5636111/) - as i'm on the topic, this one's also made by the powerup comics guy, basically continuing to be a parody of gamer webcomics... and also dilbert? i guess? fuck scott adams, by the way

8-bit theater (https://www.nuklearpower.com/2001/03/02/episode-001-were-going-where/) - i actually haven't read this one but i heard it's really good, also a very influential sprite comic

homestar runner (https://homestarrunner.com/) - this one doesn't even count (it's a web animation series) but when else am i gonna get an opportunity to bring up HSR? i mean you could treat it as a webcomic if you count the stinkoman sprite comic maker flash game or the sbemail on the topic of webcomics
