I do not have a great comparison however I upgraded my vx2 to a vx5 3x15x44. I purchased a 4.5x14x40 vx3 for my son's rifle. Both are very nice however my vx5 is much more crisp to me. Now this is the first time I ever shot a 44mm objective so I suspect that could have something to do with it. We were only at the range 1x.
Now my vx5 has a side focus and 2 revolutions on the turret. The vx3 only has 1 spin and no side focus (atleast the model I got).
I know I could have been fine with the vx3 however I dream of an Alaskan or other type of dream trip and figured I would strike with a good optic while I could so it is one less thing to worry about. Jmho.
