I've used Affinity for about four years (~2017) and it's honestly great. It offers way more power than I need for editing my wildlife photos, has a nice, familiar UI and I actually own my licences.
I use it in combination with Capture One, but if Serif ever release a tool that can manage my ~30k photos I'll definitely consider switching.
It has been a good replacement for my limited needs, give the free trial a go and see if it has all the features you want.
As a bonus it is also super cheap compared to photoshop. A permanent license right now is only $25.
