When to pick each

Pick Diamond when…

You need Obsidian (for the Nether portal), Ancient Debris (for Netherite), or you're committing to long mining sessions. The faster speed pays back the diamond cost within a few hours of play.

Pick Iron when…

You're still in the diamond-hunting phase. Iron mines every block that drops resources (gold, redstone, lapis, emerald, even diamond itself) — it's enough to bootstrap into diamond gear.
