For me, I went from Linux -> FreeBSD -> OpenBSD about 15 years ago and stayed here. I dabble in other things like Linux du jour but OpenBSD is the reliable backbone, reads partitions of other operating systems on multiboot machines (ok, not ext4). I've never screwed it up so bad I couldn't fix it.
Every operating system wants you to devote significant chunks of your life to learning it. Debian's really friendly until you break something then it's so horribly complex (that's putting it nicely) that no mere human can fix it. Searchable documentation seems to be the key, or Googling things. Searchable mailing list archives. Unless you intend to actually read every bit of documentation for each operating system you use. And by then it will have changed enough so you need to start over. -- Credit is the root of all evil. - AB1JX
