The Prometheus came out shortly after the Kraken...they both came out as an attempt to straddle the fence between gennys and drippers...they were both designed to be dual coil gennys that could deliver big clouds and big flavor..for a short time some guys were taking their Krakens to cloud competitions...also unlike most gennys at the time they both came out with an AFC that allowed them the airflow to handle two wicks with lower ohm builds. Unlike say the gennys like Doc Dave designed which did not have a huge airflow ...the vast majority of genny users don't vape dual wicks,and .8 is considered very low..Even "U" wicks seem to have disappeared among genheads. Both the Kraken and the prometheus are gennys that caught the attention of drippers far more than the attention of serious genheads.I personally think the prometheus was the better of the two...a better alternative for a dual wick genny nowdays is the origen genisis v2......
if you are new to genisis atomizers dual ss mesh wick builds can be daunting.nothing like building dual coils in a dripper.
as a single wick genny neither one of them is great,but better than alot....I didn't think they even made the prometheus anymore is it a clone? All that being said the prometheus will give you an idea of the flavor a genny can deliver, there just better flavor gennys around.
