When I go from carto tank, to Vivi Nova, to DUD I need to change wattage to get the vape I want anyway so whats the point. I thought it was supposed to vape adjustment free, but for me it doesn't.
Impossible. Even the wrap alone on the SAME Nova head will dramatically change depending on the coil placement. Then each atty you throw on vapes differently at different wattages than other attys. A bridgeless 510 will be different than a bridged, than a Vivi, than a DID, cotton, silica, ss, porcelain wicks.
Where on earth did you hear that it is adjustment free? The idea is to get you in the ballpark, not be "spot on" every time. For me, it's 1-2 clicks to "spot on" no matter which atty I throw on, which is where it should be - which is far better than going 10+ clicks in VV mode. With VW - you fine tune and that's it. There is no ballparking it before the fine tuning since VW already does that for you.
It works as intended, you just misunderstood it or were misinformed.
Edit:
Forgot to answer the OP...
Go with what you want and like. But TBH - after measuring the output of both - here's my thoughts:
You buy a Vamo for the price/performance ratio.
You buy a Provari to tell people you bought a Provari.
They are both excellently performing machines. One does more at 1/3 the price. The other does less at a far higher cost.
Up to you, not trying to ruffle any Provari users' feathers but that's just how it is with so many excellently performing mods out there now. Think i(device) vs other technology. What's the high price point for besides the logo?
