If they're all the same price, go for one with the most features that you will most likely use or the easiest overclocking features both in any order of preference. Some people have no clue about features and want to go with the most expensive one. If it were up to me I would pick the one that is the most reliable out of all 4 from research and then weigh oc reliability, then features, then pick the one suites your design/color rgb schema in that order, Good luck!
