I mainly use Vince's blue discs or Woodturners Wonders discs for power sanding.

But, I do hand sand sometimes. In the past I have used Klingspor's 2"x 10yd j-flex cloth backed "shop rolls" which are the reddish/brown color. The description states "Whether you're a turner, a carver or just need to sand that certain little spot, you'll be raving"

But, Klinspor also sells their Klingspor Gold in rolls 2" x 32ft j-flex cloth backed. Both products are aluminum oxide. The description states "This material is also used in wood sanding and is often called A Woodturners Dream Paper."

Opinions based on your own use on which one is better?

Thanks
