To be perfectly honest and coming from experience with 3.7v, VV and VW PVs, having 3000 classroom hours in Military advanced electronics training as well as 28 years practical application and a US patent utilizing that training to boot;
You can't do anything with VW that can't be done with VV.
VW ability allows you to either:
1. Not have to think, or
2. Not know how and still git-r-done.
Due to the technology available to the layman, and the lack of interest in or knowledge of the theory, ability and application of our
devices; In the end, most people keep dialing their APV until they find what they like. They stick with or around that setting and try to convince everyone else why their (purely subjective and relative ) setting is better than everyone else's. That goes for both VV and VW modes.
If you don't care to know how and why it works, then what voltage, current, resistance and power are really doing for you is a moot point. Find your sweet spot and vape on.
If you understand the differences and technology, then you can do exactly the same thing with VV that you can with VW, it's pretty much as easy as driving a manual transmission vs a automatic one. Once you learn how you never ever think about it you just do it.
If you want the luxury of an automatic tranny with cruise control then use a VW PV. If you don't mind shifting a gear stick to optimize performance then use a VV.
Note:
Most VW APVs have essentially 25 preset positions available to you, 3 to 15 watts in .5w increments.
Most VV APVs have essentially 31 preset positions available to you, 3 to 6 volts in .1v increments.
The Provari having 32 since it can be used at 2.9v
Since all cars can drive you to where you want to go, what you are really discussing now is, "How nice of a ride do I want to get me there?"
There are a few things that go into that decision:
How much am I willing to spend?
Do I want economy, luxury, dependability, high quality, least expensive to
buy, least expensive to operate and maintain, or ridiculous vanity eye candy?
All that being said (and as a non Provari owner, and maybe never will be), I don't liken the Provari to a $200k - $400k dollar car, but more to nice solid BMW. A Ford escort is cheaper and can get you any place the BMW can but the BMW can do it with more style and dependability, having more engineering behind it and retaining a superior resale value.
Why in the world anyone would start 2 different threads asking everyone to convince him to
buy a BMW because the Honda and Toyota he has in the garage doesn't satisfy his "the grass is greener on the other side of the fence" syndrome, it's beyond me. It too will turn brown if you don't water it.
I'm not trying to be mean but I will be straight; There are other ways to get attention bro.
If I can convince you to spend your money on something that would be very nice to have but you don't need, send me the cash. I've been out of work for 2 years. Otherwise just buy the thing and enjoy it.
