For BTRFS since it use of Copy of Write, it is more vulnerable. As metadata needs to be updated and more. Ext4 does not have CoW.
This is where theory and practice diverge and I bet a lot of people here will essentially have the same experience I have. I will never run an Ext filesystem again, not ever as I got burned multiple times both at home/homelab and at the datacenter with Ext shenanigans. BTRFS, ZFS, XFS all far superior and more reliable.
