Since many Vikings start with a Flint Spear and become familiar with spears, the bronze spear is a natural upgrade path.
Spears, in general, have an awkwardly short-range but their special attack and one-handedness make up for it. If you dislike the short-range on spears, try out a Bronze Atgeir. If you dislike throwing your spear, try out a Bronze Mace or Bronze Sword.
