let me just say that both taste pretty good...but steve is better by just a little. i feel like sometimes the eastmall ones are a bit TOO harsh at times, steves has good throat hit...but goes down a little smoother. Both have DECENT vapor production...SOMETIMES i'll get a big one from either, but overall, the vapor production does not compare to the 510. what do you guys think? have you guys tried the EM carts? they are alright! My friend from LeCig will be selling them too (cartomizers) for near the same price as Steve! you can get a discount code for Lecig from Vapeatron. if anyone has tried other cartomizers, please compare!
