I use the Vivinova in both VV and in the standard Ego batteries you can definitely tell the difference. I mean it works fine but its better on a higher voltage If you invest on the Vivinova and like it I would suggest you get a Variable Voltage battery, you will like it, right now in madvapes they have the spinner for $20~$25 so its not a huge investment.
(I use the Nova on the spinner and it works great at 4v with the 1.8om head)
