Is FreeBSD 12.3 more stable than FreeBSD 13.1 ?

Because why keep two branches alive. It must be there is a good reason ? Which is what i want to find out.

It may not have been your intention but the latter concerns a downgrade: not supported. Also, you'll be confronted with significant problems. For example: if your FreeBSD is a ZFS based system, you'll be trying to switch (again: downgrade) from an OpenZFS (FreeBSD 13.1) to a non-OpenZFS (FreeBSD 12.3) based system. Apart from that important particular fact, if your ZFS pool allready has its ZFS properties upgraded to the new ZFS version you cannot go back.

Perhaps a more practically relevant question—as 12.4-RELEASE is coming soon—would be:
Why would one switch from 12.3 to 13.1, instead of upgrading to the next minor version: 12.4 ?
 
Every release follows the same release engineering process, so every release is expected to reach a similar level of "stability". .0 releases might be an exception sometimes because they inevitably contain code that was only tested on -CURRENT before entering release engineering and a few BETA and RC versions that are also only tested by a small subset of users.

So, why multiple "major" branches?

This.

A new major version introduces "breaking changes", this often means extra work for an admin upgrading installations. A new minor version, OTOH, introduces new features, but only in a non-breaking way. FreeBSD guarantees that each major branch is supported for (IIRC?) 5 years, simple as that.
 
_martin, my /sbin/zfs is a softlink to /usr/local/sbin/zfs belonging to "openzfs-2022082900_1". I consider it mature enough.
 
On desktop it's Ok, I'd take that risk. On servers? I want my peace at night. I'm not missing out any features on 12.x I can't live without. I'm looking forward to use native encrypted datasets on 13.x (or possibly 14.x) but I'm happy to wait. I always loved FreeBSD stability. Since 10.x it got a bit worse (I hit few bugs in PF, ZFS that made my a lot day worse) and I'm one those you'd call: conservative. How much ?Well I still use WinAmp with the default skin.
