I’ve been working in horror lately, it’s small enough that a new series like mine can stand out but popular enough that you can get some decent traffic. The biggest downside right now is that I have to compete with like... 3(?) Premium comics. Which have a pretty big advantage when it comes to the popular/trending tabs, even beyond the additional marketing they get. But from what I know that’s pretty low compared to what the other genres have to deal with.
As always just make what speaks to you tho
