What's more effective for flavor tuning vv or vw?

[Earthling789]

Either... but I prefer VW so I can set the preferred Wattage, and the device will adjust the Voltage appropriately according to the resistance of my coil for a consistent vape.

Wattage and Voltage are interdependent on each other, based on Ohm's Law.  With the coil being a static variable, adjust either Wattage or Voltage, and the other must change to balance the equation (in simplest terms).

If you know Ohm's Law, you can set your voltage on a VV device to provide the desired Wattage.
