I've had both, the audioquest does seem a little nicer, I've had the decca and ps audio as well. The disc doctor, with his lovely cleaning pads for your vpi rcm recommends the audioquest...
Audioquest vs Hunt EDA Mk6 record brushes
I am currently using the Hunt record brush but would be interested in others' opinions about alternatives like the Audioquest or Acoustech Big. The Hunt works fine but occasionally leaves some dust on the LP forcing me to sweep again. Is any of these much better than the rest? I'm embarrased to say that I used to use my VPI 16.5 before every play but now use it only once and the Hunt and a Milty Zerostat before each play.
