the first quad I owned was a Gaui 500X. decent for what it was at the time it was introduced, but the cost was around $1000.
2 years later and the Phantom was released...orders of magnitude more sophisticated, flew better, easier to modify, change flight characteristics and half the cost. Liked it well enough that I got another. Then bought a 550. One of the Phantoms and the Gaui have been sold, the other Phantom is for playing around and introducing others to UAVs. I've flown the Blade too; it flies well, but has a "toylike" feel. The Phantom transmitter looks toylike, but it flies like a much more serious aircraft.
I have several Blade heli's, and like them a great deal. For multi's though, I'll stick with DJI
