Yup. Night and day. It's still not going to satisfy those used to Photoshop or rely on cmyk tools and support. Though 3.0 is supposed to make major strides on that as well as non destructive editing IIRC.
It is powerful, but usability is as shit as it always has been. Except for specific use cases Krita is the way to go nowadays. Even if it's focussed on digital painting, it has almost everything you need for digital editing as well, with a much more user friendly UX.
I use it a fair amount. But I think the name is still an issue for some people. They should change it to GLIMPSE. GNU Libre Image Manipulation Program SoftwarE ... or something
They said 3.0 this year a few months back. I think you could have rebuilt GIMP on GTK4 in the same time it's taken them to try and port the project up to GTK3.
