I personally hate the concept of a rolling distro, which is what the ports tree really is. Except for the things I care about, I don't want random stuff changing out from under me.
Some ports upgrade 15 years ago failing led me to rage-install Linux and run Linux on my desktop for 10 years because I just didn't have the time to deal with upgrade failures and X not working. Thankfully, now that we have ZFS boot environments (making rolling back easier), I'm back running FreeBSD. But just 2 days ago, I was left with a non-function system when a pkg upgrade renamed "startkde" to startplasma-x11 or something, and it took me nearly an hour to work out that it wasn't the nvidia driver crapping out, it was just that my 'exec startkde' in my .xsession was failing.
(Yes, I'm aware of the quarterlies, but that's about 8x too much change for me).
However, that's my fault for not reading the release notes beforehand. I wasn't frustrated with FreeBSD. I was frustrated with myself for not reviewing those release notes. Spending 5-10 minutes checking out those notes would have saved me the hour spent troubleshooting that problem. Now I always read the release notes before running updates/upgrades/etc. As a bonus, it's good for discovery of new/updates features.
IMO, OSS documentation is one of the major areas where there's a large gradient when it comes to quality. When there are projects like FreeBSD and OpenBSD that write good documentation, it's definitely worth it to take advantage of it.
You should use Ubuntu LTS if a major release every 6 months is too much for you.
A better type of benchmark is the more realistic stuff TechEmpower does, but they only test web frameworks, not OSes.

I'm aware of academic research regarding HPC and superoptimizing, but no one has applied that to generalized distro testing, so far. (At least not in public.)
I think this should be a hook in some reproducible build system.
But everyboody seems to have caved in against the complexity explosion this would involve. And build times.
OpenOffice, Firefox, Chrome, KDE, Gnome....the HORROR!
Why is that a problem? From a 3rd benchmark point of view testing the official tarball is the most relevant point to test for a Linux using audience. Different distros has different patches. Some don't even patch the software.

tl;dr optimised freeBSD performs as well as and even faster than Clear Linux on lots of benchmarks - easily faster than most distros then.
