Totally different classes, the bayangtoys is a brushless copter while the sky viper is a very lightweight brushed copter. Brushless will have an insane amount of power compared to brushed motors. Plus the ones on the sky viper are tiny.

The sky viper will hold well in crashes, you can pick up the non-gps version at Walmart. It's a kids toy so its made to be durable. That being said..if you're crashing your GPS assisted quadcopter you're already doing it wrong. I'm not really sure what applications a brushed GPS assist copter has though. It isn't powerful enough to carry any sort of payload and the camera quality is limited severely by that fact. Maybe useful for learning/tinkering with the code without the blender-ing capability that brushless motors have I guess.
