There are some that go the high volt/high ohm route, and I'll take a stab at explaining why. I rebuild my atty using 25mm of resistance wire, and get 1.5 ohm, and 3 volts is what I like (2 amps, 6 watts). If I used 50mm of resistance wire, I would have a coil twice as long, but 3 ohms. To get the same amount of current through this 3 ohm coil, I would need to run at 6 volts. (2 amps, 12 watt). This 3 ohm coil running at 6 volts is equivalent to running two of the 1.5 coils end-to-end (1.5 + 1.5 = 3 ohm, 6 + 6 = 12 watt) at the same time, doubling the amount of
eliquid vaporized (coil is longer too). So, no, it isn't just breaking even.
Another way folk try to get improvement is to lower the ohms and stick with the typical 3.6 volt battery. This is accomplished by using less wire in the coil (giving more current and more watts), using a heavier gauge wire (less ohms) with the same length, or putting two coils in parallel (sometimes called dual-coil), so there would still be 3.6 volts across each (equivalent to 7.2 volts if the two coils were end-to-end).
I find that the type of atty (I'm currently 100% rebuildables), wicking (cotton or silica or stainless-steel mesh), ohms, coil length, coil diameter, wire size, etc., all affect the quality and flavor of the vape. Combine those variables with voltage settings, and there is no 'one' answer. Each combo is 'different'. You may not like what I like.
