Hey, whatever keeps you off the stinkies! 
I actually prefer pure mechanicals and fat, juicy SLR coils now... but like I said: Try what I did. Take the *same* battery and *same* atty, put them in your provari, set it for 4.0 volts (or whatever), have a friend who doesn't vape listen to it. Now put that battery and atty in a different VV mod and repeat... Or use a mechanical and hope you can figure out how to set the provari to the same voltage... then repeat. If I had a free beer for everyone that couldn't *hear* the difference that I've tried this on I wouldn't have time to be typing this right now.
I am NOT trying to come down on Provari! They have the best warranty in the business and that never comes cheap. They build an excellent metal tube with a switch in it... but it's STILL not a magical flying unicorn. As a life long union member I feel a bit guilty every time I buy anything that *isn't* American made (like Provari). Even though I will probably never find reason to buy one I *still* have recommended others skip the vamo, zmax, etc. and buy one anyway, on a case by case basis. However there is no thermodynamic reason why the same coil, at the same voltage (everything else being equal, like corrosion, juice on the 510 connector, voltage drop in the circuit, etc.) should perform any differently at the chinese 33.3 Hz version of averaged PWM or Provari's *filtered* version of the same thing. It's a battery in a tube with a circuit that attempts to modulate the voltage to the coil to provide even heat and thus, an even vaping experience.
If you love your Provari and it keeps you off of cigarettes then that's money well spent.
