bcachefs on Arch is a bit better supported, we have the distro package maintainer in the bcachefs IRC channel, and I've never lagged on mainline support like ZFS has.
replyActual distro support, and doing it right with people actually communicating with each other, has always been a priority for the project.
btrfs has one critical issue they don't fix: it blocks access to fs for minutes if you remove large files. I am not sure how this is acceptable for prod grade fs..

replyHow large is large? I've deleted files with sizes of tens to hundreds of GBs and not seen that, and can probably whip up a test with a single-digit TB file if motivated.
Do you perhaps have 'discard=sync' in your mount options, or are using a kernel earlier than 6.2, which is the version -according to the docs- where async discard became the default?
Only if you have quotas enabled IIRC.
