Counter-rotating is more stable in the air. The one thing that annoys me 
about mine, though is the precession it seems to exhibit when hovering. 
But, it does seem easy to fly, and it is very stable. I've not had a 
chance to fly a collective pitch bird, though. So I can't say whether 
it's easier or not.

Thing is, if you're disoriented when the helicopter is facing certain 
directions, counter-rotating rotors won't do you any good :)

The one I have also has a gyro built into it's control board, so as far 
as yaw goes, it's rock-solid.
