I would have to choose GIMP (in spite of this awful name) because that page loaded without javascript and the photoshop page requires me to enable javascript.
I know I’m being a bit facetious, here, but… Adobe can afford to hire full time front end devs and designers. FOSS projects can’t really compete with Adobe’s investors.
You’re right. I wasn’t familiar with rawtherapee but just seeing that home page immediately clued me into the fact that it was some kind of image program. Didn’t even need to read a single word.
Come to think of it, there have been a number of times where I’ve wondered about what a foss project does/looks like and I think a single screenshot would’ve just been a big help in understanding how it behaves.
