Sorry after using and seeing all three the Drift HD is better all round.
Crisper, clearer images, water proof without any new cases, long life battery, takes up to a 32G sd card and takes the knocks (mine got up close and personal with a tree).
The new one is even better and if size is a factor they now do a small version but it won't take the long life battery.
I have mine mounted on the helmet off road and on the mirror on road.
Someone had them on trade me but i imported mine from Canada.
If you need to compare or see what you will get check this web site out (where i got mine)

They have all you need, good prices and fast delivery, good after sales service.
