1) Isn't the end result generally the same as a variable voltage? By that I mean that, in the end, both methods allow you to adjust your PV to provide more or less power to the carto.
The end result, as far as I'm aware, is the same. It's just the method that is different. In VV you are manually adjusting voltage to the given resistance of the coil to increase or decrease the wattage to your preference. With the VW, you tell it what output you want, and it will make internal adjustments to the voltage for the desired output, regardless of the resistance of the coil.
2) Doesn't this sort of automatic adjustment described for the Kick prevent you from dialing things into your taste? If there is some circuitry the is doing this, I am not the one deciding; it's the circuitry.
The initial setup to your taste will probably be a bit of a pain... You'll adjust the pot, screw everything together, and test. Unscrew everything, adjust pot, screw everything together and test. Rinse and repeat until you hit your sweet spot for that
juice. But after you've dialed it in, you won't have to go back in and reset it, no matter what resistance coil you attach to your PV. If you set it to let's say 9 watts, it will be 9 watts with a 1.5 ohm atty/carto or a 4 ohm atty/carto automatically.
I hope I've explained it a bit better, and if not, I'll leave it to more experienced users
The only reason I haven't purchased a Darwin, is the looks. I personally can't stand them. With the Kick (hopefully out at the end of the month), I'll have the same tech as the Darwin, in the kick-... sexy package of my GLV
