I voted traxxas nitro rustler. All rtr stadium trucks will have about the same durability. So I voted the rustler because it is the fastest out of the box. I own an hpi nitro mt. I think of the ones you have listed that is the funnest to bash because it is 4 wheel drive over 2 wheel drive which will allow you to do more things with. This car isnt race legal because it is a 4wd stadium truck but I am hoping that roar will make a racing class for these as more and more companies are jumping into this asped of stadium trucks. If you went with an mt I would highly recommend the nitro mt .18ss edition since you will be installing your own electronics. If you plan on putting any hop-ups on and plan to race in the future I would go with the xxx-nt. If you plan on putting hop-ups on just to bash I would go with the rc10 gt.
