I have a pair of Zoom Victory spikes and they are worth the money. I'm a 400/800m guy so i just wanted a fast spike with excellent grip, and fair enough I pr'ed MANY times in these. It mainly depends on what events you typically run and also personal preference. With the Matumbo's you sacrifice grip for weight and cushion. More cushion and less weight? you might ask, yes, the Matumbo IS lighter than the Victory but only by a marginal amount, a mere 2oz. Overall with both though you might sacrifice durability since they are made out of a type of nylon and wont take POWER stress (i.e. 200/400m) to well, but nothing to worry if you are solely distance.
All of this put simply:
Speed+Good Grip+Minimal Cushion+400m-1500m=Victory
