PSK1000 vs DC needle wheel, which quietest?

[dudedudedude]

I am going to upgrade my skimmer to either a PSK1000 or a DC3000 or possibly a DC6000 Jabeo and was wondering which one would be quieter? I would significantly dial down the speed on the DC6000 if I where to use it.

Input from anyone with experience with both would be much appreciated.
