I find Clip Studio lags at high resolutions with textured brushes, which is kinda a must for me, so while I know it's what I should be using long-term, I'm sticking with Procreate for now. At least until I decide to spring for a new desktop setup. Fingers crossed for more layers and comic-friendly features in future Procreate updates!
As for adjacent apps, I'm a huge fan of Artpose Pro. I really like the realistic anatomy it has, as it gives me a solid foundation to stylise as I wish, rather than giving me a pre-cartoonised figure. I've been in quite the art block these last two weeks, and having a good posing app to use as a crutch has been am absolute lifesaver.
That's about it for comic creation. Just those two.
