For most quiet, I'm still in the wool puffs camp. Real, 100% wool... hush puppies currently in use, also had excellent results with Bateman puffs (which led me to the hush puppies).
If you tie them on, rather than into the string, they're easy to adjust.
Had a bow that came with the scallops. They were very clean on the string, and easy to adjust, but cat whiskers were more quiet. And the Bateman puffs were more quiet than the whiskers.
I guess, like so much of this stuff... it depends.
