I wouldn't say a manual out performs an auto. They both give very different vaping experiences, even beyond the act of pushing a button. A manual is much less resistant to damage from leaking, this much is true. But the pleasure I get from vaping on an auto far outweighs the benefits of any manual I've ever used, to the point that I have given away or traded all of my manuals. Right now I'm dipping on a super mini because this is the only method to keep me from craving a cigarette. And I used to drip on my manuals, but I still smoked while doing so.
