Gimp for a full image manipulation suit.
Krita for digital painting/art and a decent gui, still better for light image edits then paint.
Between those two photoshop is essentially overpriced hypeware. Its convenient to have both foss apps packed under a single well designed interface but no where worth what they demand. After adobe leaked the details from my student account back in 2013 they have continuously caused me so much damage they should be paying me.
I actually use gimp in a semi-professional capacity. I have access to photoshop but I find Photoshop to be very unintuitive whereas Gump has all of its layouts exactly where I expect it to be after a few years of usage.
There are some things that photoshop does better than gimp. It’s magic select tool is light years better than gimps, and content aware fill is also light years better, but I, who only need to make occasional minor edits to images to present them to other people one time I’m able to accomplish everything that I need with free software, and if it were up to me alone I would discontinue my Adobe subscription.
