The biggest difference in the stainless and aluminum is Stainless props are usually more aggressive due to they are Cupped and Aluminum props aren't. The cup gets you out on plane faster and helps when in rough seas or pulling skiers to get a good hard low end thrust. The stainless is used more for salt water use due to sand bars which kill the aluminum props but dosn't hurt a stainless plus salt eats up and away an aluminum prop. personaly i only use stainless on all my boats but keep a cheap aluminum for a spare in case were to spin a prop.
