I actually use Paint 3D
As it does just one thing I want which is to rotate and paste my logo onto a thumbnail / cover image for videos. Otherwise I use paint.
I am sure there are free alternatives that would do that as well or better, but I don't need everything they do, and I would have to learn how to use them, whereas the free already included 3D paint does the job and is good enough for what is strictly a hobby.
