In my experience, I got better battery runtime w/my VTC Mini using VW than I do using TC (on the order of 5-7 minutes longer per battery). But there are variables/differences like the resistance of the builds (lower ohms in TC), the wattage ceiling used in TC as opposed to what I used in VW (higher ceiling in TC). Now, using a smok Treebox, I get horrible battery life in TC. Even set to "Soft", it gives me right at one half the time that I get w/my VTC Mini using same atty and build! Basically little to no difference in juice used over the course of the day using either mod.
Coil and wick life is a LOT better in TC. As is overall "vape experience". In TC, no worry about a dry hit- no matter how long of a draw is taken.
