So you want chromed brass, which is the shiniest and most durable material.
There are also stainless steel versions, these usually come from China and, almost unbelievably, lots of Chinese stainless steel is very poor quality, and will either get patches of corrosion, or black pits.
European Stainless is usually 18/8 or 18/10 (percentages of chrome and nickel in the alloy) and Chinese is often 18/0.
Nickel is a relatively expensive alloy, so leaving it out cuts the cost and the quality.
