I won't speak for GSOM but the Zing is a very cool not so little knife. Great ergonomics, unique blade, perfect edc size. Not to mention choice of styles in either handle material (Zytel or G10) or color and blade shape. The Zing changed my opinion of Zytel. (I'm sure no one here ever thought twice of a "plastic" handle, right?)
Do I have a favorite? The green G10 with black tanto blade is one of my most carried as is the orange Zytel with striated blade. Never carried the damascus though it would look really cool in orange or green scales.
