ZFS will still be preferable for production for a long while until bcachefs has proven itself, and bug reports slow down. That said, I'm also stoked for bcachefs.

ZFS has always appeared to me like a bloated mess. Btrfs is more minimal, but too much so, in that it doesn't do parity (at least very reliably), which sucks because I don't always want mirroring. And it has a reputation for gobbling your data up.

If bcachefs can provide all the most useful features of ZFS, while being minimal and baked into Linux by default, man that will be amazing.
