Our current recommended file system of choice is XFS.  BTRFS is not supported and will result in a loss of performance.  Moreover, Suse does not recommend keeping data on BTRFS and will create XFS volumes for /home and data.  In this way there is no data loss on a rollback.  (These recommendations also apply to Red Hat.)
