The Losi XXX-SCT is the strongest of the bunch without any doubt.
The new TLR 22-SCT is about to hit our shores and will be a serious contender for racing and will be also very strong going on the 22 design/quality.
If you specifically want an RTR car then i would wait for the new Durango as the price is very reasonable considering the quality of electrics included and the truck is a strong one with a race pedigree.
The Blitz is a good starter truck but doesn't seem to hold up in competition against the other trucks and has a few mechanical faults/weak points
Ansmann X2SC/Team C cars are very competitive racers and easy to drive/set-up but again have weak points.
Depends on your experience and what you will be using it for?
