My feeling is that there is. I think it all started with the speed I can login over ssh. Debian always seems to have a short delay but FreeBSD feels instant. When it comes to rating FreeBSD as a better OS for servers I may be biased as Debian has served me so well over the years. I was never a Docker fan but instantly liked Jails for isolating services. Then we have native ZFS support which simplifies my backup needs. A simple zfs send | zfs receive and you have an exact copy of your service instance on a remote node. Everything feels integrated and not stacked. Again, just a personal opinion.
That’s one of my dilemmas. Due to using BSD and relying on jails I have a hard time using lots of possibly nice apps being released nowadays because they only offer the docker way of installing.
