I have never owned an Xray car, so I cannot really comment on the XB4, but a lot of people over here do race them. Apart from the problems the XB4 had in the beginning, it seems to be a strong car, although not bulletproof: I often hear them rattling like a coffee machine. The newly released gears will probably fix this. The S104 however, sounds really smooth and silent for a gear diff car.

There are a lot of things I like on the S104. The thing I like most for instance is the fact that it will just turn better than most(if not all) cars on the market. It is easy to drive and gives you a lot of confidence. After the third ever lipo with it, I was already faster than with my K cars.
