Yep, here are the factors IMO.
- Best for budget = P1
- Best for flight time = P2
- Gimbal support = P1 or P2
- Built-in FPV = FC40 (no gimbal, no tilt) or P2V (no gimbal, with tilt) or P2V+ (built-in gimbal, with tilt)
- Easiness to install a gimbal and FPV = P2 + Zenmuse + AVL58 + iOSD Mini + FPV Hub
- Most expensive = P2 + Zenmuse + GoPro + LightBridge
Gimbal = 2/3 axis stabilization = stable/smooth photos/video.
P1 = Phantom 1
P2 = Phantom 2 (2.8GHz Edition aka Non-Vision)
P2V = Phantom 2 Vison
P2V+ = Phantom 2 Vision+ (latest model)
