Verdict
Diamond hits for 7 vs Iron's 6 — a ~17% damage bump — and lasts 6× longer (1,561 vs 250 uses). Worth it the moment you have 2 diamonds to spare. Diamond also accepts richer enchantments via the Smithing Table upgrade path to Netherite.

When to pick each
Pick Diamond when…
You have at least 2 diamonds and aren't saving them all for a pickaxe. The damage edge and durability mean you can fight bosses (Wither, Iron Golems) without breaking mid-fight.
Pick Iron when…
You're still diamond-hunting. Iron is cheap, smeltable from any iron ore, and good enough to bridge until your first diamond. Don't waste your diamond on a sword if you don't have a pickaxe yet.
