There is a blog that pops up quickly if you search for reviews on the Cryo. The blogger bashes the Cryo as a travesty but in a review of the Zing SS calls it "what the Cryo should have been" so anyway, since there were not comparison pictures here I did everyone the favor and ordered both knives 
Stats on size, weight, ect are all on the internet so I won't duplicate them here.
The Cryo feels slightly shorter in hand although weightier, the Zing feels "light for length"
and the big reason I carry the Cryo more often than the SS Zing
I originally owned and returned a Cryo because I felt it was too short to get use to. Now I carry it daily. I like the weight and blade shape of the Zing SS but I absolutely despise that style of clip. I think they are completely different knifes and one doesn't really replace the other. The Cryo is built very sturdy and I think that justifies the weight. I'm not a real fan of the lighter color that the Zing SS is but that's just aesthetic as well.
Other opinons may vary but I wanted to address the straight up picture comparison for anyone looking at choosing between the two.
