10 is OK if you remove the ads and stop random update. I’ll never use 11 and beyond. I always switched to Linux for my dev box and now that I play less and less game (haven’t played for weeks) I’ll switch to Linux for my personal box too, once the current one broke down.
Windows 10 Pro is actually a pretty decent OS. It brought quite a few major improvements over Windows 7 and I can't really think of any notable downsides.
