If you just want to crop and adjust levels, GIMP is fine. If you want to clone stamp or replace backgrounds etc (or of course work with motion graphics) then there’s no comparison. Nondestructive editing has been a HUGE drawback for GIMP since its inception but they are finally adding that, which is good. I’m not even sure if they’ve added CMYK support. Text editing is also godawful. I could go on, but for real work, it just isn’t the same at all. It’s like saying an e-bike is the same as a pickup truck.
