1) the smell...it's very similar to the smell of the original bars + a pungent chemical smell, which I assume comes from the gel ingredients.
2) I can't use this on my face/ears (oily areas)...the bar cleans these areas nicely, so that the are "squeaky" clean w/o overly drying.
I guess it's all about tradeoffs. Overall, I prefer the bar. I can use a loufa to exfoliate.
