I think that for most people the easiest of the two to fight would be the zombies. But on the other hand I think most would agree that spiders are more useful. Yet for experience points or if you don’t have a village nearby i think zombies are more useful, you can get iron, carrots, armor, potatoes and tools from zombies. But you can get spider eye, for potions, and string. So what do you think is more useful, zombies or spiders?
