The ones with a double row of short grounded conductive carbon fiber brushes work well IMO.
The original Decca and Sleeve City brushes are the ones I use.
The brushes on the Audioquest are too long.
The brush must be used properly. Lay the brush on the record at a slight vertical angle, and slowly tilt the brush in the opposite direction of record rotation, then lift off. Hold down the brush gently! Do not slide the brush as the collected dust will be dragged into the grooves! Then turn the brush in the holder to knock off the collected dust. You can see the collected dust on the brush as evidence of effectiveness.
