Arko vs. Proraso. Anyone care to offer a comparison?

In my year or so of wetshaving I've used Williams Mug (meh) Col. Conk's (OK, but I think the Bay Rum irritates my skin) and Proraso soap, the green tub. I prefer to face lather, and Proraso has been wonderful stuff. Love the scent, love the rich lather. I've been hearing good stuff about Arko (aside from some not liking the scent), and the price point is...very appealing. Anyone care to share comparisons of the two?
