To me, the main and nearly-sole advantage is maintenance. Little need to wipe it down after handling and even then a dry t-shirt will work just fine. Makes for a nightstand gun that isn't likely to get any oil on whatever it touches and isn't going to rust on you. A minor second advantage might be less wear visible from holstering a lot.
I have a 40-yr-old nickeled snub and there is some clouding on the grip frame but that is all.
If I were going to buy a non-blued gun and could find it in satin stainless, that is what I'd buy. Just my personal preference.

Reason: typo - satin vs stain
