Best combination to replace my MGM/NEU 1515 2.5d

Yes, the MMM is much smoother than the MGM and has a lot more programming features. With the MMM it is much easier to tune your brake and throttle profiles to act exactly how you want them to the T. You will find that the drive characteristics greatly change for the better with the MMM.

I have owned both, and while the MGM is a robust controller, it is nowhere near the controller the MMM is.
