I couldn't agree more. For me personally there are times where I look back at other Operating Systems and how much they infuriate me for one reason or another.
The perfect Operating System does not exist whatsoever. But if I had to say which Operating System is closest to perfection it would have to be GrapheneOS.
From Security to Stability to Compatibility to Ease of use to Privacy to overall Usability to Control. It strikes a very amazing balance between all of those things despite the main focus being Privacy and Security. Whereas with other Operating Systems I personally have yet to find another OS that can actually match that level of rational balance.
GrapheneOS is the only Operating System that doesn't frustrate me whatsoever. Been a proud user for nearly a year now and I haven't found a single thing that makes me want to leave.
