I haven't ran these personally side by side so I can't give you an answer. The Tmaxx is fast though. The Savage is a fast truck but you are now comparing two different scale MT's The MGT is in the same class as the Savage but is slower. Granted the MGT has a 21 and the Savage now has a 25 ( soon to be discontinued) and the 28. It has to do with the gearing of the Savage and the Tmaxx. I think the Savage in its present state has more tunability than the Tmaxx. The Tmaxx has greased diffs and can't use Diff locking silicone oil. The Savage can. I think between the two the Tmaxx is faster from separate expereinces. I have had the Tmaxx and enjoyed the speed but the Savage is a damn strong truck in power and durabilty.
