different people have different opinions on this, but here's mine: there are different kinds of vapes (hot, warm, somewhat cooler, etc) and there are many ways to achieve those different vapes. 3.7 w/ a LR atty, 3.7 w/ a standard atty, 5v w/ a standard atty, 6v w/ a standard atty, 5 or 6 w/ a higher resistance atty, 7.4v w/ a HR atty, and of course there's VV to play around with the numbers between 4 & 5 or 5 & 6. then of course there's also the difference between
vaping w/ an atty vs.
vaping w/ a carto...the list can go on and on. the point is to find what works for you, and i tend to find that i'm happiest in the 9-10.5 watt range, w/ a 510 atty most of the time, be it low res (1.5-2 ohms) standard (2.2-2.5 ohms) or slightly higher than standard (3-3.5 ohms). here's a link to a great calculator to calculate watts, amps, volts, or ohms (you put in 2, it solves for the rest):
Ohm's Law / Watt's Law Calculator.
of course, remember that all
devices are not made equal, so the same voltage will likely vape different on different devices (resistance of the mod itself or the circuitry involved is mostly to blame for this).
hope i was able to answer your question, and sorry if it got long-winded
