For my experience my previous ESC was TEKIN RSX pro, Toro, Orion r10 /r10.1, Team orion HMX , HW XR10 pro G2 and last Pro-performance ESC. Only team orion can closed to pro performance that i like. The pro performance is great for stock and MOD compared to HMX and HW XR10 G2. Also pro performance is great for support and services Brian Mills is a great guy he can help you how to set up your ESC also if your Radio Sanwa/M17 their servo is great up to date i can feel the difference from my MKS servo, protek servo. Pro performance servo feel more connected to the car it seems i was inside my buggy very interesting if you bind in steering to SXR take advantage for racing.
