I don't think that goes hand in hand with any photo software
I could never get used to PS, and have been using Gimp for well over 10 years, but I agree it does take some learning, but to me a lot less than PS.
For basic work, I don't know what can be found difficult with Affinity, and when I don't know how to do something, I am surprised how simple it is when I search youtube.
However, when ever you look on any forum, you will find people who seem to have all bad luck with software, and others who think it is the best thing since sliced bread, the only way to see where you are on that scale is to try it
