Scott (and others): Since you are now in possession of all 3 WOWA's which do you prefer? I've been using OS and CS for some time now. While differences are minimal, I'd give the slight appearance edge to OS and a slight durability edge to CS. My question involves Ultima. While I'm aware that Ultima is 12 oz, as opposed to 8 and 6 of OS and CS respectively, is Ultima really 1500 to 2000% better, as indicated by the price? If it really is better, I'll go for it but seems to me that for a few bucks more, I can get 3 bottles of OS or 2.5 bottles of CS! Your opinions, please?
