For me, its a twofold thing.
First part, is the vape satisfaction.
If we're talking PURELY vapor production, ie: Cloud Swag, then yeah, some of the higher wattage regulated devices can beat mechanicals.
If we're talking about the vape itself, FOR ME, a 1.8ohm coil pushing 30, 40, 50watts, is NOT the same, as a .3ohm doing the same/similar. It might look like you're putting out the same, or more vapor from the 1.8ohm build, but the vape is different.
And from what I have tried, I can't get the vape I like from a coil with that high resistance. Believe me, for practicality purposes, a box mod with dual 30amp 2600mah batteries, or better, that could provide the vape I crave all day, well that would be handy for certain situations.
The second is about the device itself. Vaping for me has become so much than just not smoking cigarettes. I am extremely happy that I actually HAVE quit smoking, I mean I truly never thought id be able too. But I have, and thats awesome. But the other part for me, are these handcrafted, smartly engineered and expertly executed ideas some of these mod makers are able to put out, that Im very much drawn too.
Im often accused of being a snob when it comes to things I like, and hey, if thats true, so be it. Life is not forever, so while Im here, Im going to enjoy the best, whenever possible. For vaping, TO ME, the best right now, is not stolen chinese counterfiets, or regulated tube and box mods, its the high end, inspired, expertly crafted mechanical mods. Actually you know what, there is an exception. I dont use it nearly at all these days, but it still falls in the same category as expertly crafted. Provari. Its probably the only non mech I wouldn't give up.
Thats me anyway.
