I use Clip Studio for a lot of stuff. It used to be Manga Studio until they rebranded it not too long ago. The comics industry has been using it for quite some time now. Fast, stable, great brush rendering engine, AND you can make vector layers to draw in, in which all the lines you draw can be edited with the anchor points and bezier tools. So far, i’ve used it as the first draft of all my projects. Highly recommended.
