Go for the original (blued) look if you're a traditionalist!

The shiny guys tend to be called "pimpgunners" (in my circle anyway)!!

Seriously though, if you have the choice, stainless every time (despite the "label") - so much easier to keep looking good.

My pistol, Pietta .44 'Texas' looks really tatty after lots of hard use - blueing well worn and the brass frame is a real pain to keep clean. Still shoots well though.
