I like reiserfs and am using reiserfs3 for my journaled partition. 
But speed wise it is actaully the slowest at deletes.  But that said,
it has other features I like.  It can be resized up OR down in size. 
I actually used this durning my last upgrade where I took some space
from my video storage to use for installing a new distro for rebuild. 
I think that xfs can only go larger in size..
