So you're saying the high drain is worth the less power (will die quicker) to have it consistently give enough power? I gotta go on dealextreme I guess haha
it's a trade off really...depending on which atty you're using...and LR atties are the worst senario
the Li-Ion batteries are 3.7V but the amp draw you put on them exceeds the max drain rate of the battery so what you get is actually voltage sag (they won't really perform as 3.7V) and you overstress the battery which cause the longevity of the battery and it's ability to hold and store a charge to decline....
the high drain IMR have a lower internal resistance and a safer chemisty which allows them to be discharged at a higher rate so they will have the power to make that atty perform at a true 3.7V (they'll hit harder)..additionally they wont be overstressed so they will last longer as far as longevity goes...however the amount of time on a charge (your vape time) will be less than fresh Li_Ion...
this of course all goes out the window with 18650 batteries where the high drain IMR batteries are just overkill...even the regular Li-Ion batteries have enough mAh to them to overcome the Amp draw problem
