Not to throw a wrench in your gears, but you shouldn't buy either.
These are not highly supported at most hobby shops, and upgrades are not going to be as universal.
I would go HPI, LOSI, or even Kyosho before I would pay less for one of these.
Save your money up and get something higher quality and you wont be sorry.
And just so you know, I am not speaking outa my *** on this either.
I have over 15 years RC background and ran a hobby shop as lead tech.
