I moved away from Windows as much as I can and now I maintain a dualboot just for Photoshop and Lightroom. I think compared to average people I’m doing quite well conviction wise.
I also use Gimp as much as I can. Unfortunately for processing hundreds of photos Rawrherapee + Gimp is not a viable option for me. There are problems both with quality and speed. (Gimp is the problem for speed and RT or DT for the lack of quality due to weak highlight reconstruction)
I would argue that it’s either a 4-6 way tie, or Meta is the worst, but MS is certainly terrible.
