I used it as an installed desktop environment at a workbench in a non security context for a year. It was a pain in the butt in like a million ways.
Even when I used the tools kali ships with regularly I either dual booted or ran it inside a vm.
If you wanna understand why every time someone asks about using kali as a daily driver even on their own forums, a bunch of people pop up and say it’s a bad idea, give it a shot sometime.
