I only have 4 hours of games and I have 22 points in swords

Either way, I like Swords better for the hero as the best weapon is also a sword. By the end game spears get a little behind, but mid-game and metal slime hunting they shine.

pick spears you dumbo
but actually this is a classic rpg, choose whatever weapon you like
Spears help with slime hunting, though the 3DS version adds a couple of characters that can help with that too.
