I use Clip Studio to do my initial drawing & inking...I then transfer to Photoshop, where I do most of my coloring; I toggle between PS and CSP to get the colors & the effects that I need/want, and then transfer a copy to Illustrator where I do my lettering. I then merge the finished copy & lettering in Photoshop, format it and, and it's ready to upload.
CSP does lettering, but not as well as Illustrator. CSP has issues with fonts that have auto ligatures, as well as some kerning & spacing. Photoshop does lettering, but PS is raster based- which means the more you manipulate the finished art, the more it tends to pixelate. The only other program that comes close to Illustrator in terms of quality vector based lettering is Affinity Designer(original price $50; was on sale for 50% off until 6/20).
Lately I've been doing a lot of standalone pieces mainly using CSP- trying to get myself to color more with the program. I'll probably still use PS to color my comic- mostly because I have the brushes/tools that get the effects to do what I need; but with each new build of CSP, they are catching up to a lot of what Photoshop does better than them...when that day arrives, then I'll gladly drop PS entirely.
