Not a coincidence that most of what you listed is done by Patrick Fillion, I feel like he's the only one who takes his comics/art super seriously and at least TRIES to include some sort of cool themes in his porn comics. And his art is super high-quality and top notch imo.
Tom Cray does Jox and Alexander does Star-Crossed and Super-Hung and you can tell how much more bland their comics are compared to Fillion (both in art, story, concept...). Like they kind of just draw the comic for the paycheck.
Granted though, Patrick Fillion owns Class Comics and so it's pretty much "Patrick Fillion comics, feat. some other guest artists". I'm pretty sure there are many other great artists or gay porn comic creators out there that he and Class Comics could benefit from hiring.
They release a new comic every what, 2 months? And each probably sells on average 100? I'm actually not exactly sure how Fillion and his husband have managed to keep Class Comics to stay afloat for this long, he probably makes around $2k/month on Patreon which is barely enough to get by.
