When to pick each

Pick Iron when…

You have smelted iron. The damage and durability bump make caving and overworld combat noticeably safer. Two hits to kill a zombie matters when you're swarmed.

Pick Stone when…

Day one of a new world, no iron yet. Stone is cheap and fast to craft from cobblestone. Replace it ASAP — its only role is bridging to the iron tier.
