For those of you looking for adobe alternatives the affinity suite is quite good too, I don't think it is open source and it is not free but you can make a lifetime license purchase that is not really all that expensive, I think it is one of the best adobe alternatives at the moment because it is so similar both in tools and the ecosystem.
At the moment the rest are all ones that compete with specific adobe apps like darktable being better than lightroom as an example.
I like gimp but all of these software alternatives will just land in a similar spot where the only cohesiveness is that the files can be exported/imported between eachother.
I always describe satisfactory as subnautica but about automating machinery like a tycoon game but with more reminiscent of portal. Needless to say its really fun!
