I always wanted to get into bsd, especially openbsd. I like the idea of a more cohesive os.
But I don't really know what to use it for to get started. My desktop runs linux with steam for games. My AI server needs rocm drivers so ubuntu-server. My vps runs debian, maybe that one, but there is no DO image for BSD. Open for ideas..
FreeBSD would work well for your purposes, it has a really good hypervisor and linux abi compatibility
OpenBSD for the layer where you need the highest security. We use it for hosting our Postgres clusters. You could easily use it for your VPS. There is a learning curve. But if you’re already comfortable with Linux you’ll pick it up in a few hours.
