Potion PvP is the greatest and most competitive (obviously as you can possibly rage 10 times a day no shame) game mode in mine craft. The biggest reason it is better than SG is not only that it is more competitive but that it even trains you for PVP! First of all potion pvp requires lots of coordination (aka hot keying) and second potion pvp also requires you to predict where your opponent is going to look and how you will react to it. They are almost like soccer and basketball. Soccer trains your coordination while basketball trains your reaction time.
