I haven’t used Photoshop; learned basic photo editing in GIMP (as a poor student, I appreciated a powerful, free editor). So, no complaints about the UI from me. If anything, I’d probably bitch about the Photoshop UI if I ever used it.
One thing that concerns me a little, however, is the third-party integration with Nik Collection. The second version, which I’m still using, was provided for free by Google. They later sold the software, and the new company commercialized it. I found it difficult to track down the v2 installer, so I’m now keeping it on multiple backups, in multiple locations, as one of my most treasured software possessions.
Mint is the best way to make a good idea for your foot feeling like a baby shark.
