I wish GIMP had a full UI redesign like Blender, it could work as a Photoshop replacement for many use cases but… Jesus it’s non intuitive, flawed and it mixes opposing design principles all the time.
There was a project that renamed it to a less controversial name and updated the UI to more closely resemble modern photo manipulation tools, but they’ve stopped working on it before a major release.
EDIT: There’s PhotoGIMP by Diolinux, a Brazilian Linux YouTube channel with a really nice host. This is a set of plugins and configuration files that try to ease the transition from Photoshop to GIMP for newcomers. It’s certainly good, but as an add-on, it can’t actually fix all issues with GIMP.
