I've had a couple of each of them and really it just depends on how you drive and what kind of power you put to it. The arms and diffs are the same for both trucks if thats what your asking. My emaxx was my race truck and i raced it in the local T maxx class and won with it many times due in part to the smooth transition of power, it can be made a very nice handling truck.

Really about the only problems i had with the E maxx was after i put mod motors and 3300 packs in it the stock sliders would not hold up, after about 2 weeks of qualifying and racing i would pull the sliders apart and notice they were begining to twist ALOT from the mod motors. CVDs ended that problem. Other than that i stripped a couple spur gears and broke a shock end but thats about it on the emaxx.

If you get a emaxx then more than likely you will be bit by the mod motor & hi powered pack bug after awhile so one word of advise. Look into a comm lathe if you get mod motors, i had to cut my comms about every 8 runs with the motors i had to keep full power. Its a pretty good truck though so have fun with it if you pick one up
