i may get turned into soylent for this but, i think it's mostly a matter of knowing how to tweak things. someone that just started recently didn't have to learn how to maximize vapor production and throat hit within the really narrow confines of 510's,901's and 801's. it's waaay easier to just be able to hit a button to up the power range to compensate for substandard setups in other areas now without having to figure out how to get a good tasting,satisfying vape on locked low voltage.once you learn how to replace cigarettes with a 510 or old school ego and a cart,bvc's and adjustable power are just icing on the cake.
