Lens choice help - 55-300 or 70-300 (Nikon)

[RubyX4]

I have a D5000 with (currently) 55-200 AF-S VR. It doesn't have quite enough reach sometimes so now I have some spare cash do I get the 70-300 which I've read some great reveiws on or do I get the 55-300 AF-S VR II?

I do nature/aircraft/transport mostly.

thanks
