The Axis is very straight/neutral. It wants to hold it's line of release to the end of it's flight. The Axis is slightly faster than the Vector with slightly more glide, so it flies farther with less effort.
I agree with this assessment.
The Axis is a max weight super stiff Glo Buzzz - they fly almost exactly the same to me (and I'm very loyal to my Glo Buzzzes).
The Vector is a Roc that went to school and learned how to fight wind better. It may take more power to throw than your garden variety DX Roc though.
