Netherite Sword vs Diamond Sword

Minecraft 1.21.8. Java Edition values.

Verdict

Netherite wins on every spec: +1 damage, +470 durability, and the item survives lava and fire. If you can craft it, switch. The only real cost is the netherite scrap grind — about a stack of ancient debris for a full kit.

When to pick each

Pick Netherite when…

You're in the Nether, fighting bosses, or anywhere a dropped item might hit lava. The damage edge also matters against high-HP mobs (Wither, Ravager, Iron Golem).

Pick Diamond when…

You haven't reached the Nether yet, you want a backup that won't gate your gameplay, or you're enchanting first and upgrading the material later via the Smithing Table.
