I loved Arko until I started using Williams and found that it works better, way better. I'm kinda bummed because I have a lot of Arko.
Arko is a good soap in my books but not enough to call it great. If you are strictly looking at it from a price point of view, yep, that one is amazing. If you look at the lather+scent, then no, it's not on top of my list.
