Would you rather take Leather or Gold armour?
You can make limitless amounts of leather armour by killing a bunch of cows, but has a lower level of armour than gold. Gold can sometimes be hard to come by.
leather, reason in survival games leather armor is more common than gold in chests
also with a looting sword and a good cow farm its MUCH more easier to obtain than gold
also fortune picks don't work on gold so there you go leather ftw!
