Generally the only reason people use stainless is for increased performance due to a thinner blade, which decreases drag and rotating weight. Usually lower hp motors don't use stainless because they don't make much of a difference in performance and are obviously more expensive. An aluminum prop might be painted, so when you flirt with the bottom you may lose paint and it will not look as nice as a stainless if that matters to you. But as far as durability, I'd say they are similar. Both will bend like a pretzel if you hit something.</p></blockquote><p></p>
