Norton Speed Disk 2001 or Diskeeper 6.0?

[Biggs]

Which is faster, better, more efficient, and takes the lesser memory footprint, system resources, and cpu cycles?

I use them, but I recommend the Norton because, I have some troubles with diskeeper ( some freezes and crashes in a quantum hd ), the norton also is more fast than diskeeper...so, I prefer the norton.
