Servers are a different story but for Desktop, OpenSUSE.
Because:
Part of my transition from Windows to Linux was that basic tasks like installing software or even the OS itself shouldn't be a high effort endeavour. I should be able to point to a package file or run a package manager and be able to go about my day without running "make" and working my way through dependency hell.
I say this as a Linux user of all different flavours for well over 15 years who has a deep love for what it brings to the table. If we want it to be common place with non-IT folks, it needs to work and it needs to be simple to use.
I liked LEAP when I tried it a couple of years back. They're getting rid of it soon, and I don't really like rolling releases so probably won't try anything SUSE any time soon.
