the first 1 is good. the 2nd one is a super racer. same thing as bensu, and charge and go. they're both ok. i think preciuos has a better rep. they're both fast, but from what i've read, the first one is better quality. i have a few of the super racers. they're just ok. if you get a chance go for a shen or rally racer. much, much, much better.
