It also depends on what tank you are using. Some tanks perform better at higher wattage, like the TFV8 for instance. It performs better at roughly, ( just off the top of my head) 120w, for a sweet spot. What it really boils down to is what you want out of your vape. If you are going for more flavour than anything else, then higher ohms are best, conserving battery life. On the other hand, if you are going for more clouds then you will want lower ohms thus needing more power and using more juice.
Me personally, I like a balance of both, so I run around .2Ω alot of the time using stainless steel. That gives me a good balance and doesn't drain my batteries quickly. I do have to change out my batteries later on the day, but if you vape alot you might have to sooner. I vape at around 60-80w most of the time using a dual battery mod.
So in short, what is it you are looking for? There is no wrong way to vape really. The right way to vape is whatever way keeps you off of the stinkies.
Vape on, Vaping saves lives.
I'm not crazy, my mother had me tested.
