These is an overall focus in the matter too often not considered, while it's pure reality check. That said, I hate concept art conceived that way, am a full brush illustrator. For this, Photo beats ANY of the tools mentioned in the thread, except Photoshop. More often with a combination of techniques so that it is fast but looks well. Concept art can be done 'illustration style', or pure matte painting, or even just photo bashing. And than in Designer, actually, particularly, as you mentioned illustration and concept art. It is an indeed total requirement in most of the companies across many fields, so, if anything, you can indeed rebuild those workflows in Photo more likely than in the eye-candy traditional painting specialized tools. Significant amount (if not massive majority) of concept artists in video game companies, with all the money that the industry handles.

Photo is VERY similar in functionality to Adobe Photoshop, and trust me, there are legions of professionals working with it ( I have, for decades) for digital painting. While is very, *very* rare for me to disagree with you, I have to, kindly, in this one. For illustration and concept art Affinity Designer might be better for you than Photo.
