Each has its own advantages.
It doesn't matter what basket, aluminum alloy and stainless steel are, as long as you are satisfied and comfortable to use.
But overall, you can have a look. Most people are still willing to accept the stainless steel perforated type. After all, it looks generous and neat. The basket looks a little messy from the outside.
Baskets are mainly produced by many well-known foreign manufacturers, so most domestic manufacturers follow suit. In fact, the material grade can't meet the requirements of disinfection. I can't say more about this either. I'll figure it out myself. I understand when different types are used too much.
