I started learning docker, kubernetes, Linux etc before I even knew what a jail was. I remember trying to decide how to deploy nextcloud, whether as a plug-in, or using this script
Once I learned BSD and jails, I’m now leaning towards “if you can’t run it on BSD, you don’t need it 
(kidding, I realize the need for diversity)
I’ve used both CORE and SCALE and because of what I already know, I’m sticking with CORE. SCALE for me has been that (OP) on and off, trying each new release, finding CORE still my choice.
