I'm deciding on which types of mob farms to really get into, I would like to narrow It down to one main one. I've heard these three are really efficient: iron golem [ig], creeper, and cow. I have a minimum of one of each and they all work well for me, regardless. I've heard many people say that one or the other is the best, but if anyone has exact calculations or proof which one is the all-time best no matter how many you have, please share it below.. I want to know which type to really invest into, but I'm not sure at all. I've had great luck with all three types, but cannot afford all of them at once. Thank you!
