When you ask a question like this you need to put what kind of car u plan to put it in. It would be decent in 2wd but, the only people I see that try to say they work in 4x4 sc have not ran anything else. They will work but you will have to do some testing and tweaking to get them to work decent.

The MMP is an OK ESC. There are better options though. The Speed passion reventon Pro is in the same price range and is all around better speed control. It is smoother, just as adjustable, a better bec. There are others but without knowing your application its hard to say.
