I can't believe I read this whole thread. Maybe I just like the discussion huh?
There can be criticisms laid at any of these devices. But they all vape, and vape an order of magnitude better than the equipment on the market when I started vaping. So regarding the OP, when people get to "fanboish" I write it off to not really knowing what they are doing or lack of critical thinking.
The Provari is a formidable PV, and if you have the money it's a no brainer. But that's coming from a guy with two Lavatubes (Black and Pink), three kicks (Telescope, Empire Mod, and Bombshell Stinger), an Imotion2 V+, Provari, and a zmax v2 (RMS Version) in my "regulated collection".
The Imotion2 V+ is pretty much the only price/performance dud (My opinion). Haven't used the new zmax yet... but we'll see.
I did a three part series on regulated vaping a while ago which might interest some people watching this topic. The second two segments are perhaps germain to this discussion:
