Walker or VPI motor controller with scoutmaster?

I currently own a scoutmaster with super platter. I am considering purchasing either the Walker or VPI motor controller. I tested the speed on my turntable using a strobe and the turntable operates at the correct speed. In addition, my turntable is plugged into an isolated wall socket that is on a separate circuit from the rest of my audio equipment. In addition, I only have 33 rpm records.

I am not sure the Walker or VPI motor controller would benefit my system.

Is there anyone with a similar setup that has tried either the Walker or VPI motor controller? I would like to know, if anyone with a similar setup has experienced any benefit from either a Walker or VPI motor controller.
