Hey guys, now that my 6yo son has gathered some rc hobbygrade experience (he drives pretty good), he's ready for the real stuff.
I'm gonna buy him either a 1/16 Grave digger rtr or a 1/16 summit vxl rtr.
Terrain will be mostly grass, dirt, forest, some schoolyard.

which one would you buy, and WHY?
Thanks in advance for your answers!
