SC10. This is mine on the way to TQ and win in the 2wd class last time I raced it. 'Nuff said LOL. Seriously though, all of the 2wd trucks are pretty good. I love my SC10, but you need to understand and like setting your truck up, because if you miss, it's awful. From what I hear, the setup on the FT kit is pretty good right out of the box. That wasn't so with the early kits or RTR trucks, don't know if they've changed it in the newer RTR. The Traxxas is probably the most forgiving of the trucks, but doesn't have nearly as much adjustability as the others. Haven't driven the Losi, HPI, or K-car, but have raced against them and they all looked good on the track. If you go with a RTR, go BL if you can. I'd check track rules and parts availability where you plan to race and see if that makes a difference.
