If you only use it once yeah. I'm super casual and just use it for cropping and resizing and whatnot, and have used it dozens of times. Worth 20-30 minutes.

I am a digital artist and I've been using Photoshop since 2000s. I still find it infinitely more comfortable to open mspaint and do quick resizing or image editing there.

When I forced to use gimp I simultaneously want to a) kill myself b) kill developers of gimp and their family members.

Well, it depends on what you're used to. Although I'm just a casual user, I've been using GIMP for years, and had similar feelings to yours when I had to use Photoshop once.
