Not sure where you've seen it, because it sure wasn't in my post.
I've tried the alternatives. I once (regretfully) paid for Pixelmator. I tried Krita. I suffered through GIMP. I've fiddled with Clip Studio Paint.
Photoshop is quite simply better, more full-featured, and stable. Pixelmator would crash fairly often and I'd lose progress. The others just don't have good UI, and in GIMP's case, it's outright user-hostile.
I've managed to switch most of my software to free/cheaper alternatives (Blender has improved a lot lately and I was glad to leave Maya), but when it comes to 2D art on desktops, Photoshop is unfortunately still the best.
