After Reiser ("The Killer Filesystem") became defunct... I jumped over to XFS 
for my Myth rig.. worked great. My current load I went back to ext3 (just to 
try it on Myth) and it's a nightmare for handling large files. Forget it. XFS 
seems to work best for me.. and I'll never trust a first generation filesystem 
like ext4. Especially ext4. ;)

For data recovery.. I really like ext3 for being able to mount read only, as 
ext2 or  recovery tools like ext3grep... it rocks (from a recovery 
perspective). Just sucks for large/many file applications.
