Ted Tso will tell you that ext4 is only extensivly tested in the simple cases (single drive, home system type of thing), while XFS has had a lot of attention and testing on very large and sophisticated drive systems, so the larger and more powerful the drive subsystem you have the more likely you are to run into some corner case that the ext4 developers just haven't run into yet, but that the XFS developers have handled.
