Which do you prefer...

This is actually kind of tough.

Humans..
Pros: Control of positioning in water, fast on land, have swords, can block projectile weapons with their shields
Cons: Slow in water, cannot dive for pearls, fewer hits to kill than bomys, only one useless hacky sack.

Bomys..
Pros: Fast in water, heal in water, heal with bombs, more hits to kill than humans, four useless hacky sacks.
Cons: kicking is not very effective, slow on land, cannot block projectile weapons

When I have enough time, I'll make a more accurate list. I choose bomy for now, though.
