What is the difference between the stainless steel and aluminum Apple Watch?

I'm getting ready to buy an Apple Watch

I saw that there were both stainless steel and aluminum that felt like iron.

Is there any difference other than other ingredients?

Aluminum is good for exercise

Stainless steel is strong, but it gets scratched easily
If you're worried about scratches, I recommend it

I'm using aluminum, and there are a lot of scratches on the screen
If I buy it again, I think I'll buy it

I think it's best to feed aluminum with care plus
