I'm no gun expert by any measure but I've seen many fingerprints "burned" into blueing whereas I've never seen that on stainless. I am not the type of person who handles my guns with gloves and tissue therefore I get a lot of fingerprints on them. And I've been known to forget to wipe it down after hunting, especially if I'm going back out later.
No matter how good I clean it, I always end up with a fingerprint on it and I'm always wishing for a stainless, powder coat, or teflon finish. As a matter of fact, I've just talked myself into never buying another blued gun
