Danaher vs Curtis controller for golf only

I am purchasing a used RXV to refurbish. I can get either a 2012 with the danaher controller or 2013 with the Curtis. It's going to used for golf and neighborhood transportation. Speed is more important than torque to me. It won't be lifted but will have either 18.5" or 20.5" tire wheel combo with 6 8v batteries.
Which controller would you suggest I purchase
