I could use Photoshop in my art creation, but I refuse to. Affinity Photo is good enough and doesn't cost a lot. I might miss a few features but my life is more pleasant without Adobe.
Due to my past experiences, I have not used it in a while, but I have always hated it (and that is not something I usually feel towards software). Such a terrible UI for a product related to art development is baffling.
That said, I understand there is a ton of open source engineering that goes into it, and I have a great respect for the effort.
It is not like people couldn't create beautiful pictures before those non-destructive layers.
People tend to complain about some so called missing features while they were living happily without them when their favorite software didn't have them too.
