It was designed to primary not lose data from the very beginning. That was at the very core of every design choice. Maybe there were a few such bugs but I have not read of any, while in comparison Btrfs I have read a whole of them.

Compare how bcachefs/zfs approaches these challenges and then go back to the early years of Btrfs. There is really no comparison.

I don't disagree that maintainer-goals and practices make me trust ZFS more. They do. But there have been bugs. Last major one I remember in the core code is this one:

But there was a Linux-specific data loss bug with ZFS in 2018:

Of course you should use what you like. And I agree that ZFS is safer. But again, I don't know of any file system that can say it has "been stable from the beginning", if stable means no data loss.
