The way I see it... 901 version will be about equal. (3.7v) - but I believe Prodigy will last 2-3 times longer, due to the battery size. Some are saying that SD last about 8 hours +... Prodigy probably would last even longer than that, thanks to the longer battery.
Prodigy's power will really shine with 6v, as it seems - with 801 atomizer, as seen on the video.
If you have multiple atomizers laying around - prodigy might be a better option, especially 401/510 users as well - so that you'd be able to just switch the adapter and
vape.
For people in US, Prodigy is also cheaper option. SD, which I've ordered a couple days ago, is about 160+ dollars including shipping - so Prodigy is cheaper.
But, it does seem Prodigy is a pretty big unit - maybe an inch longer than SD, perhaps. As per aesthetics, it's very subjective... I'm planning to get a Prodigy in near future, probably 801 or maybe 510 version when it comes out. I haven't ordered prodigy yet - but I ordered SD instead, as it's an already proven model to be an excellent e-cig, although I"m quite sure that prodigy will be aa great, if not greater e-cig in terms of performance.
