Well the brushless is fast but im not sure if its faster than the 2 speed with an os. The nitro is nice because you can run as long as you got gas, and its cheaper to get into. But the brushless is nice because it has instant power and its plug and play. Having both is sweet, ill always have nitro or gas cause i love em, but  i can run the electric at night or when i just wanna run real fast or something.
