In terms of performance, I woud say that a hydraulic disc has a ever so slight advantage over cables. I cant put a reason to it, but near enough every hydraulic I've used was solid as hell all the time. My front bb7 however is exactly the same, i dont think a rhino could budge it, it locks SO well. Just my back one is a bit iffy every so often. So all in all, Id go for cables because they're easy to tinker with, cheaper, and give a very similar performance
