If you use GIMP and Krita together, you can get like 80-90% of the features photoshop had

The main problem for me is that GIMP has no equivalent to content-aware fill, so the closest open source equivalent to that afaik is using krita's AI slop stable diffusion plugin to generate fill ins, which takes much longer to generate and comes with its own foibles

this is coming from someone that uses graphic design software primarily to make memes though so

while making this comment i searched online and apparently GIMP has a content-aware fill esque plugin called resynthesizer, idk if its any good but if it is that is huge
