bsdtar can create .tar.xz archives with compression level 9 (at least it 
claims it does, I added --option xz:compression=9 or so) - however, if I 
unxz them and xz -9 them again (or do that to any tar archives), bsdtar 
cannot extract them. This is the same for -7 and -8. pacman is therefore 
also unable to read those archives. No idea why, but I thought I'd 
mention it.
