I recently made the move to Affinity Photo. The latest version gives me all I need. Muscle memory is still with Potatoshop, but I’m slowly transferring.
An advantage I will say is that if you have more than two machines, Affinity doesn’t make you do the license login song and dance. Because I am frequently using at least 3 computers (and often it’s 5), I like that I don’t even have to have Creative Cloud installed on everything, because it’s just easier that way.
For me, Adobe is still better in some ways/more familiar, but Affinity is getting so close that I’m very happy we have this sort of tool as an alternative.
