I have used btrfs on Fedora for 5 years, with transparent compression enabled and have not once had any kind of data loss. I also use it on servers used in production in RAID 1 (on ones that don't run VMs or Databases) and again, have not had any data loss or filesystem issues. BTRFS has so much faith that Facebook use it on their server farms. I wouldn't use bcachefs in any kind of critical deployment because it hasn't gone through decades of testing that ext4, xfs and btrfs have gone through.
