As a multi-decade Photoshop user, I find Affinity unusable. I know it comes very highly rated, but my muscle memory is so ingrained that I don't think I can make the switch. Not a single thing worked the way I'd expect, and trying to adapt to it was hours of constant digging through forums to do the most basic things, like move the canvas.

I started using Krita instead, and it's a good replacement without being so utterly different.
