- I feel the HH65 controller is better than the one built-in to the RHH135 - it has more subtle movement.
- The RHH135 pad itself is probably "nicer"?
- If your hat stand has an adjustable tension on the spring you may like this. Obs the HH65 lacks this,
- Moving hats are anachronistic anyway - and just to appease old-school acoustic drummers
- If you're a gigging drummer, the RHH135 means you have to carry an extra hat stand.
 I own and use HH65 + various pads, RHH130 and RHH135.
