Why the switch stuck
Nothing asks me for money on a schedule. That is the honest headline. The software opens, does the work, and never shows me a renewal notice or a plan comparison. For someone who is not billing full time in a design tool, the arithmetic of a subscription never worked out.
It launches fast and stays out of the way. No background updater, no sign-in wall, no separate desktop app whose job is managing the other apps. Photoshop's startup has become a small ritual of its own. Affinity opens and there is a canvas.

The three apps share one file. Photo, Designer and Publisher read each other's documents. In current versions you can use another app's tools inside the file already open. No export step sits between raster editing, vector work and layout. That removes a whole category of mistakes.
It is enough for the work I actually do. Cleaning up screenshots, building assets, laying out a page, fixing someone's logo. Nothing in that list needs the deepest Adobe features, and I found that out by doing the work rather than by comparing feature tables.
The parts nobody warns you about
Colour codes spend most of their life as text moving between a design file, a stylesheet and a chat message. That handoff is where the format mismatches happen, and it is the same in both suites.
Your muscle memory is a real cost. Years of Photoshop shortcuts do not transfer cleanly. Affinity's own defaults are close in places and different in others, and for the first weeks you will reach for a key that does something else. You can remap most of it, and I would rather you know that the first fortnight is slower.
The answer to your problem is harder to find. Twenty years of Photoshop tutorials, forum threads and StackExchange answers exist for every obscure task. Affinity's community is active and much smaller. A niche question sometimes returns no result at all. That gap says nothing about software quality. It counts how many people have already been stuck where you are.
Ownership changed under it. Canva now decides the roadmap. That may be good for the product and it removes the argument that Affinity is a small independent bet, and it means the terms you buy under today are Canva's terms, not Serif's.
