I've only owned Traxxas and Losi, so my vote goes to Losi. With Traxxas I kept breaking parts. Losi Muggy > Revo, it doesn't have the nifty suspension design but it is FAR more durable and still handles offroad very well.
Lol thats funny. My experience is the exact opposite. Every losi I've owned was pathetically weak, and I bash my traxxas cars harder and am yet to break a thing...
