I had a system which had apparently worked OK on Ext4 but had some memory 
errors.  After twice having a serious BTRFS corruption (needed backup-format-
restore) I ran memtest and found that a DIMM was broken.

In that sort of situation it seems that BTRFS is likely to be more fragile due 
to the more complex data structures and due to the fact that it's a newer 
filesystem with less corner cases handled.

That said, it's working well for me on a few systems without ECC RAM.
