I have to disagree on that, Affinity designer and photo, publisher are not prosumer at all
, and by the way AP 1.7 can load a lot of PS brushess.
By prosumer, I meant the Affinity apps are great for people who need a Photoshop-like program, without it being Photoshop. The Pro Photoshop market I consider to be people who have workflows that require Photoshop: either a plug-in or a brush that that doesn't work with Affinity. Or, it uses Photoshop actions that don't work at all with Affinity. A lot of these workflows are built around squeezing every second of productivity out of a tool, or being able to call someone 24x7 for support when the thing breaks. Or the time cost to moving to a new platform doesn't outweigh the financial savings.
Affinity also can only use .abr brushes. I think when Kyle's brushes weren't part of Adobe they couldn't be used in Affinity because they were tpl brushes.
Every now and then I come across some cool Photoshop effect. I will post on the Affinity forums for help on doing this with Photo, and the answer sometimes is, "You can't."
I get that some people don't like subscriptions. I use the Affinity products because the Adobe subscription isn't valuable to me. However, I do pay a subscription for apps that I need for a workflow, and the time savings using those apps provides value.
