i have the savage x 4.6 and it is much more durable than the mgt. double backflips are not uncommon with my driving
from everyday "normal person" use, i have broke nothing except for losing a couple screws. with my kind of bashing, i've broken 2 dogbones, an engine mount, a fuel tank, and a engine mount plate.
the dogbones were from WOT landings on pavement and the other parts were broken from a 25 ft. almost vertical jump with a roof landing.
the savage will take much more abuse than a MGT. the weakest links on the savage are the dogbones and some people also say the diffs. you can always use the HD dogbones if needed and the flux or CEN diffs if you have a diff problem.
