I haven't handled either, but between those two I'd pick the Kershaw Turbulence. Kershaw's 14C28N steel takes and retains an edge better than SOG's AUS-8 and Kershaws tend to come with better edges from the factory (not just in overall sharpness, but also the angle and evenness of the grind, which makes it easier to resharpen and put a uniform edge on the blade). Just my two cents.
