I have used Freebsd for sometime on my desktop back in 2021. For the most part I had a good experience except that I couldn’t figure out how to connect earphones/mic on the ports on my PC case. I had to plug it directly to my motherboard for Freebsd to detect them. I used an Nvidia card at that time and it also worked very nicely although it had much older drivers than Linux.
I ended up switching back to linux because of 2 reasons -
I have a few BTRFS drives that I use regularly and couldn’t afford to buy some new ones for Freebsd at that time.
I couldn’t play games using steam proton. I don’t know the situation these days, but I’ll surely check it out If it has improved since then.
