do you have a recommendation for a good BSD derivative distribution to try?
The thing about BSD is it’s fully POSIX compliant which can be good and bad. The good is it’s highly consistent in terms of architecture and how things operate. The bad is standards constraints can limit flexibility. Linux is somewhat POSIX compliant, but has a tendency to go off the rails at times. In any case if you’re comfortable with Linux you’ll be comfortable with BSD right out of the gate.
Linux can suffer a lot from fragmentation due it’s market bazaar style development. FreeBSD is run by a single entity responsible for design top to bottom. There’s been some big changes to Linux in modern times I don’t really care for (such as systemd). With BSD you always know what to expect. You won’t get blindsided by some off the wall change in architecture or design which happens a lot with Linux.
There’s a number of BSD distributions that are open source and free. The main open source BSD distros are FreeBSD, NetBSD, OpenBSD, and DragonFly BSD. FreeBSD is most popular and is designed to be good all around. It’s probably going to have the best device support, but other BSDs can have other strengths. For example DragonFly BSD is stronger for desktop use.
Honestly the best application for BSD is in a sever or development environment. Linux is more advanced when it comes to support for desktop use. Though I think BSD provides a much cleaner and consistent operating system as it conforms to specific standards. You can get it to work well for desktop use with a little extra work and preselection of compatible hardware.
