Well. Actually XFS has both the ability to recover from an unclean shutdown without fsck, and a full featured repair tool. Don't be confused by the fact that the fsck.xfs-tool is essentially /bin/true. The repair tool exists, but it goes by the name of xfs_repair.
I've been using XFS on Linux in production on most of my machines for the past six years or so, and have needed to run xfs_repair twice. Haven't lost any files, either.
The "it eats your filez"-reputation of XFS has been greatly exaggerated.
