I'm checking it out too. At this point I'm mostly concerned about servers though (and simple servers at that, I don't need a lot of third party software) so I think OpenBSD is a good fit there. That's what I was using Debian for all these years because of it's stability. That said even before systemd came along Debian was actually starting to bug me slightly with changes between distros.
On a desktop I don't care how fast a distro changes, I like mucking around with my desktop. And whether it was throwing Mint on because I knew it would, for the most part, Just Work or throwing Debian on a laptop and bothering with hand crafting a desktop I never worried about what was under the hood too much, just enjoyed seeing GNU/Linux mature as an end user solution.
But I don't want any of that on a production server. I want something known for stability and security and something that a mere mortal like me can understand with regards to the base system. OpenBSD fits this criteria nicely.
Despite my previous comment it's not like I'll never use Debian or GNU/Linux again, I'm just replacing my server infrastructure with something I can depend on staying consistent and stable for the foreseeable future.
Thanks for the advice!
