It’s not necessarily better, some things are a personal preference. Though some might be able to list some technical pros and cons.
Some things I appreciate are:
base systems and packages are completely separate. Packages and their configuration goes in /usr/local/ No where else. (Thought they might write to /var/ )
bsd init, not systemd. Feels more home to me as a late 90s slackware user.
first class zfs support. Linux has caught up lately, especially now that there is a shared zfs codebase for both Linux and FreeBSD. When I switched to FreeBSD on my home server ~10 years ago that wasn’t the case.
wjy would it be better

Some things I appreciate are:
Its more of a niche. You probably won’t have the huge support you have on gnu/Linux nowadays
“gnu/Linux nowadays” is unusable on old hardware (except distros like Alpine) I think?
There are a bunch of distros focused on old hardware compatibility. I often install Linux on 32 bit laptops from around 2008 and they work perfectly
