I'm guessing that Bolin's strength might come from slow-twitch muscles and Mako's from fast-twitch. Earthbending requires power and solidity, while Firebending requires ferocity and agility, so Bolin would need slow-twitch muscles while Mako would need fast-twitch. One may not exactly be stronger than the other, because they [might] have very different types of strength.
