The software itself just isn’t anywhere near the feature parity it needs to be. The UI and workflows are just not there for what users are expecting. I can’t suggest someone learn it because it just isn’t going to serve them well in the end.
But because it exists it means someone who would do it better has less incentive to do so.
Not that I consider Photoshop a good image editor anymore, over the past 8 years it’s degraded horribly. So now we just don’t have good image editors.
