I'd argue that OpenBSD would be worthy of that title, too. It is incredibly easy, elegant, and simple. The thoughtfulness that goes into all the base system utilities in OpenBSD is so appreciated.
FreeBSD is kinda somewhere in between Open/NetBSD and Linux in my opinion. Their docs are OK, but the handbook leaves a lot to be desired, and they don't seem to have nearly nice little quality of life utilities that OpenBSD has out of the box.
I spend a fair bit of time on Linux command lines, but I use a mix of different TUI and GUI editors (including ones that work over ssh for editing files on servers), and none of those are vi. I can manage vi if I must, but its an effort and distracts from the task because I have to think about how to do things in vi.
My favourite editor is mcedit, which you get by installing mc (midnight commander)
Like nano but (IMO) easier to use with a lot more features
