It is hard to state exactly the difference between an aluminum prop and stainless steel since the blade design is different.

Generally speaking stainless steel props are more efficient and durable. They will not suffer the same damage as aluminum.

Remember size and design is not universal across brands.

A Yamaha K series stainless steel 13.25x17 will not necessary perform the same as a Stilletto Advantage 13.25x17. It may be better or much worse.
