If u wanted a good off road stadium truck get the 18SS because of the 4WD and the motor that comes with it is an easy to tune motor. If you go with the jato you would probably do more racing and or on road driving. I Have the rush evo and its just rear wheel drive with a .15 motor and it flys. I got it to do some wheelies. So its up to you at this point. If you want more of a monster truck type of ST then the 18SS is for you because of the 4WD with large tires with a ST size 1/10 scale truck. Jato is like that cept with no 4wd and may be a little heavier with the ez-start system, but its not 4wd so lighter on that part too. What ever, its up to you now.
