RGB 15 pin to a HD plasma?

Has anyone used a 15 pin RGB connection from a HD satallite receiver to a HD plasma monitor?.How is the picture quality vs a 3 cable component connection? I dont hear much about using a RGB 15 pin connection and was wondering if I should buy this cable and try it.
General consensus is that three cable component is still the best way to go. My own HD projector has only one set of component inputs so I use 3 cable component connection for my satellite and the 15 pin input for my seperate OTA (off the air) reception and I really don't notice much of a difference.

I have also used both component-to-15 pin cables and three cable component to 5-pin cables with success. These are available at www.A2Zcables.com
