Your funny, I think the word your looking for is stagnant. I've never seen any substantial evidence of a distro with outdated packages really being any more reliable than a rolling release.
I've only had a Debian server for six months and have already ran into issues with botched updates multiple times on bookworm. I only use it for zfs because Debian often runs a kernel old enough to support it. I had an arch server run for nine years no issues zfs just takes a bit to support the latest lts kernel.
I've troubleshooted Debian just about as much as I've troubleshooted arch so what's your point.
