i am really having trouble on deciding which move to use for an aggron since both have their pros and cons. superpower is powerful but lowers its attack and defense everytime you use it..so aggrons high defense will get lowered and his high attack too. low kick depends on how heavy the opponent is and most steel and rock types who are weak to low kick are heavy anyway but some are really light and low kick might not do anything to them. which one do you guys think is better competitively?
