The only feature? Like across the entire OS? Pretty broad. If you were right then adoption would be orders of magnitude higher.
It's the only feature I missed. That doesn't mean that you won't be looking for something else. I run almost the same FOSS day to day on both Mac and Linux.
I've worked in jobs that only used Linux as the day to day desktop operating system. I currently work on macOS.
What features do you think are missing?
