Our current recommended file system of choice is XFS.  BTRFS is not supported and will result in a significant loss of performance.  Moreover, SUSE does not recommend keeping variable 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.)
