I used Krita last year (2016) and really liked it. I started using it more than Corel Painter because it has nice brushes and the layer support is much better. Being free didn’t hurt either as I got burned by how expensive Corel Painter updates were and felt annoyed by their sale tactics as I’d upgraded version 12 to 16 for what I thought was a good price but then they released a new version a few weeks after which made me feel really resentful and cheated as it was a better version and the version I’d upgraded to had a bug that wouldn’t let me disable the advertising popups. The latest version of Krita is a big improvement so far and now works with my Ugee 2150 tablet (with the newest Ugee driver).
