Just a quick note to let you know that Affinity Photo is currently 50% off. So if you always thought about getting a license, now might be a good time. There is also the update version 1.9 available.
I am not affiliated with Serif Affinity Photo, I am just a casual user, but I found it a good alternative with a different licensing model.
