To actually test them properly you need an understanding of Adobe's products. I only know the very basics of Photoshop - I'm guessing most are in the same position
I do want some open source Adobe suite clone to work. I just have far more fate in tools like Krita that don't give me a feeling of being fooled and sold a toy even if it's free.
In fact the open source project is there for profit as the easiest way to install it is to go to their website, where they also offer AI credits to use with those tools from $8 per month to subscriptions far more expensive if you need more credits.
