I first dual-booted Linux back in 2008 because I'm a musician and at the time I was a broke highschooler trying to use Ubuntu Studio to record and mix songs without dropping $500 on a Pro Tools license. After that I'd generally always have a dual boot system because I like using Linux for its flexibility.
Back in December I switched to 100% Linux Mint on my main gaming PC because my Windows 10 install was starting to die in all kinds of ways and I was gonna have to reinstall, so I just formatted the partition and went all Linux.
I also self-host a bunch of little servers for various stuff on like 5 different little single-board-computers (Pi 4, M1 Mac Mini, etc), and they all run various flavors of Linux, mostly Debian and Ubuntu but also Asahi on the Mac.
In general I find it waaaay easier to maintain, update, repair, and modify. Package managers should be available for every OS by default, not as an ugly hack like on Windows or MacOS.
