What does not need fsck is journaling filesystem, which includes XFS but 
also ext3fs and ext4fs.

What does need fsck is (for non-journaling filesystems) interrupted 
writes but also (for journaling filesystems as well) other causes of 

I suspect your description of XFS use implies running xfs_check only 
manually - i.e. comparable to "tune2fs -c 0 ..." for ext3fs and ext4fs.
