i used krita. it has a lot of features, some are uber amazing, but, the menus are simply not friendly, working on krita is slow and tedious, menus and sub menus, windows over windows, a mess.

csp is the best for FAST WORK, SPECIALLY SEQUENTIAL WORK, but, personally i think SAI PAINT TOOL is way better than csp for basic and to the point illustration (sai´s shine layer mode allows you to create the best shines and lighting effects i have seen on digital art) and the ability to create custom brushes is epic and perfect, you can create the brushes you want, csp is barely starting to allow such customize freedom.

csp is focused on speed of work, i mean, their new a.i. shading system literally saves lots of worktime, which you can use to make more pics or pages in less time.

to finish, for me, these are the best digital art softwares and why

SAI PAINT TOOL, if you are going to make illustrations only, sai is the best, easy to use, friendly to use, and the layer modes are amazing. also, sai has the best pen stabilization system i have ever used, even better than csp's. sai's pen stabilization tool is like having LAZY NEZUMI PRO already installed and working all the time, for inking and final lineart, epic.

CLIP STUDIO PAINT, for professionals, artists that draw daily, artists with a deadline, csp is about workflow speed, work well, work fast, and now that the one payment deal is back, then yeah, if you already own it, keep it.

SKETCHBOOK PRO, for sketching and basic illustration, yes, you can make very complex and amazing works there, but sketchbook pro is aimed at artists that work fast and easy works, but want professional results.

sorry if too long, it is hard to find artists that talk about the software they use.

No worries; I don't mind the geek out over software.

Too bad, I think I will stick with GIMP.

Nothing wrong with that.

I've been using the same programs (including Paint) for a long time - the learning curve and expense for some of these new programs is well beyond me, so I applaud your decision to stick with what works for you. Your art looks good as it is!

Aw thanks Cap!

I have use clipstudio paint for four years. They do offer a diverse upgrades for the brushes, background and other tool for animation.
