well they are 2 different catagories of trucks!
which is more fun depends what you want to do and what you like to do.
for me the MT is better because I have a driveway and I like drifting it and bashing onroad as well as off
for my best friends the savage is better because he lives in the middle of fields has a dirt driveway and has little interest in racing around on paved surfaces
SO WHAT DO YOU LIKE TO DO????
