Few reviewers have noted the magnets for the battery doors falling out with the Vmate. Not sure if Voopoo has addressed this or not. Something to consider. Personally I would choose the Luxe
TC is short for Temperature Control. In order for TC to work, the coil must contain either Stainless Steel, Nickel or Titanium. How TC works is when a coil heats up, its resistance rises by a given amount. With a imputed value based on the metal used in the wire, the mod is able to make calculations and predict the temperature of coil and in doing so it will attempt at keeping the coil at the temperature you selected. Many opt not to use Temperature Control because they feel it is too complicated.
Cloud production is about vaporizing the most amount of juice in the shortest amount of time and getting that vapor into our lungs efficiently. We can accomplish this with increased power and increased air flow of the atomizer. However with increasing power we also increase the likely hood of burning the wick. Trust me, you do not want this!! Along with heating up the atomizer to the point where it is too hot to use. So a happy medium must be found. It becomes more difficult to achieve that happy medium with a coil that has a large mass for it takes longer to heat up and cool down. Little more complex than this but that is the short and simple explanation.
If looking to achieve the most amount of clouds efficiently I would look at the Wotofo Profile Mesh RDA. The large surface area of the mesh maximizes vapor production. And given the mesh is extremely low in mass in comparison to a coil, it is more efficient – ie: heats up and cools down quicker. It's operating range is lower, 40 to 70ish watts but this could play toward extended battery life.
The challenge with mesh is that it is less forgiving than a regular coil. It is critical that your cotton (wick) is tightly pressed against the mesh surface otherwise you create a hot spot which leads to a dry burn. The Profile mitigates this with a pressure plate under the wick that is constantly pushes against the cotton. Each RDA comes with their own learning curve but the Profile is not difficult to build on. However it does require much more cotton than a typical coil. The bonus to this is the cotton lasts much, much longer providing you do not burn it. The mesh strips for the Profile RDA are inexpensive and should have the same life span as a typical coil. You can purchase cotton strips made specifically for the Profile that removes all guess work out of wicking. But even if you use typical cotton like Cotton Bacon, you will quickly learn how much cotton is needed in order to mitigate dry burns.
Just to note, mesh tends to consume more juice but if your objective is cloud production, it may even burn less than a typical dual coil running at 100+ watts (I am guessing!)
The Profile RDA can be used with any mod that allows a power setting of between 40 watts and up.
