Forget which is better, it is totaly opinion. They are both great buggies, one not better then the other. Both have there stong points and weak points. Chose the one that fits your driving style and parts support for your area. I as a matter of fact just finished building a new FTB4.1 today, that is what I like, that is all. The Kyosho SP2 is sweet as well. I think shocks are better then both Associate and Losi, but my opinion only. You will not go wrong with either of the two.
