The way releases are done and security is handled, one can argue that it makes sense to stay one major version behind - as long as it is a version to which security patches are applied regularly.
I follow this rule, or the variant where you wait for the first point release of a new major version, wherever possible. My desktop ran Debian bullseye until maybe about a month ago, when I updated to bookworm on its 5th point release. My browser of choice on that machine is firefox-esr, which is still on the 115.x branch.
I'm updating to bookworm on my daily driver laptop today - testing the full system backup now.
I've had minimal issues recently with debian but decades of debacles (not just debian, everything from RSX-11 to windows server) have made me cautious. So exhausted with wasted time.

Do you have experience using "Debian LTS"? It might have gotten me to stick to Bullseye for a little while longer, but I don't know much about it, and EOL was coming along soon.
