Armor is a progression check
Armor is less about finding one permanent best set and more about matching your current biome. If a normal enemy can erase most of your health in one mistake, your armor or food is probably behind.
Heavy vs light choices
Heavier sets usually reward direct combat but can change movement feel. Lighter options can be better for exploration, ranged play or experienced players who avoid hits consistently.
When to upgrade
Upgrading an existing set is often cheaper and safer than entering a new biome undergeared just because a new crafting recipe exists.
