GIMP

Ahh, if Gimp was a type of person easily identifiable by an outward trait, I would throw javelins at their cocks.
And miss on purpose if it meant getting a head shot.
Fuckdamnit do I hate Gimp. I'd rather stick my newly roused genitalia in a rambunctious beehive than ever use that shitpile again.
The asswipe magnitude of the developers must be near the MAXIMUM point, which is always serious.
Fuck Gimp. I hope they go extinct.

You might be able to get similar end results with Gimp, after more effort, and getting some additional scripts/plugins.

But even doing something simple like stroke effects on a layer is a pain in the ass in Gimp, not to mention you don't have the preview setup like in PS.

So you can adjust settings before applying, so it comes out how you want it, instead of create effect -> apply it -> don't like it -> undo -> start over
