Well, Photopea is pretty close to being a 1:1 clone of Photoshop, it's a top of the line non-destructive photo editing web app, way better and easier to use than GIMP. The only good thing about GIMP is that it's open source.
Do you do photo manipulation for a living ? If you did, you would know for a fact everything I said is true. And if you don't know what non-destructive even means or some other term that sounds like marketing speech, then I suggest you google those terms, because they are actual features. Features that someone who likes to save time on work would really appreciate.
Edit: My tier list
Photoshop
Photopea
GIMP
Photoshop web (it's like a Photoshop by Fisher Price)
