The Korkers "Jetty Plus Fishing Cleat" K1100 (there are two models of the k1100) have more and better placed cleats than the 5000, plus they can be modified to become almost indestructable whereas the buckles cannot be modified as easily. If you use the screw in spike models, you better treat the threads with loctite to prevent the threads from rusting and seizing in place. If you're only fishing from safer flat jetties, I'm sure either would be a good choice. However, if you're fishing from some of the more dangerous jetties, one you need to climb and jump from rock to rock, there's no way I would trust the buckle versions.
