For my part, Affinity does not offer me a "Plus Value" and I will stay with PSP. On the other hand, there are aspects of Affinity that I would like to find in PSP such as "Place".I will probably continue to watch the presentations made by Carole but not do the exercises.
When I take pictures, there are two important things for me: the identification of people in the photo and their geolocation. Corel has abandoned these two aspects but has kept the "Tags" of the photos (I still have the 2019 version for these features).
So I use "Picasa 3" and an improved version of "AvPicFaceXmpTagger" for the identification and creation of "Tags" and "GeoSetter" for geolocation.
I have also developed programs to synchronize the Picasa database with that of PSP. Thus, in PSP, it is easy for me to find the photos where a particular person is present.
Good luck to Affinity users.
