What is your favourite (2D) digital art program?

I use the Affinity Suite (Designer, Photo, Publisher), depending on the project type.

 

Clip studio is amazing, but I do find that for the bulk of my coloring, I switched between that and Sai, and then finished up on photoshop for some overlay affects.

 

I used to use Photoshop but I switched to ClipStudio many years back and I haven't looked back since. The cleanness of the lines, the intuitive ease of the UI, and the helpful tools have really made it both quick to pick up and effortless to use. I do sometimes miss some of the fancier effects from PS, but for lining and coloring - and even simple animations! - it's the best overall program for me, with the least amount of fuss importing and exporting between multiple programs.

 

I'd be inclined to try other programs, but as someone in graphic design the Adobe Suite is still the standard for most industries so I'm stuck paying them an arm and a leg forever.

 

Paint.NET right now. Even though, I started off with Photoshop and eventually got into Gimp. I've been using Paint.NET since roughly 2009-2010 and it works just as well as Photoshop. The best part is that it has a very large community and has been mainly an open source project and people have helped it out by contributing to the project. There's a lot of plugins and those plugins actually make the program similar to Photoshop but, Photoshop has also been stepping up the game over the years and just offers a lot more features now than they ever did before.
