The best benefit of using stainless steel is its rust proof ability. Your caddy will be covered in water every time you shower and rust can be a serious problem. Overtime it may begin to rust because stainless steel does not stop, but limits, stain, corrosion, and rust. It contains chromium that forms a passive film of chromium oxide, which limits the amount of surface corrosion protecting your metal.

With a plastic rack you may not need to worry about corrosion or rust but you can run into mildew and even mold can build up on a plastic shower caddy. The other benefit of steel is the strength; it can hold more weight than a plastic version. You also run the risk of them snapping or cracking, but due to the strength of metal you will not experience this problem.
