my vote : Super jump i didnt vote for o.p.k it takes out all the fun of the game where as super jump hiding on buildings and snipering is alot more fun watching your enemy running around like a headless chicken 
The best one has to be unlimited stamina or 100% Accuracy (which u missed out), because they are hardly noticeable if you use them correctly by other players. And you don't need a bypass to use them.
