FWIW I switched to Affinity from PS after having used PS for 20+ years (since 5.5 I think?). Honestly, it was super easy.
Most of the use I had for PS is now split between: Procreate (drawing, illustration, game assets), Figma/Penpot (wireframes, quick mockups, UI sketches etc...), Affinity (image processing, quick photo edits, batch processing, anything that doesn't fall into the categories mentioned earlier).
