IMO:

Pros - Fast, durable, powerful, big tires, big tank, just big all around, and simply just awesome compared so some similar 1/8 scale trucks.

Cons - fuel consumption is obviously high with a .46 engine, steering servo is sketchy for such a heavy truck (GST), Transmission is slightly complicated to set up and diagnose problems for beginner and sometimes intermediate users.

In as simple of terms as possible:

GST = bashing
Nemesis = racing
