I have tried Regular. It lathers well. It is cheap. It is practically scent-free, and the haters of Arko Soap should be pleased to know that. Sometimes I use it by itself. Sometimes I mix it with more expensive creams to stretch the supply. Sometimes I mix half-and-half, Arko soap and cream. I have a couple other cream varieties in reserve but have not tried them as of yet. Some critics of the Cool have said it was not "cool" as in mentholated. Usually I avoid anything for "sensitive skin". It is a good bet that performance takes a hit in exchange for some kind of "mildness".
"Adventure" has a nice mild cheap smelling mens sport cologne odor. I have the matching aftershave cream and the balm....surprised what decent performance you can get for the price.
Besides the regular Arko sticks, I've only tried the Arko Extra Sensitive which I picked up because I like the smell of lavender. It does smell faintly of lavender and is a good performer for the price.
