Everything you ever wanted to know about Sig owners fear of stainless slides eating up the anodoized cover of their alloy frames
(both the current and the German Sigs when they were sprinkled with magical dust from yesteryears and stainless frames too)

A point of reference in all this, a stainless slide is somewhat typical. A stainless barrel is somewhat not typical. Non SS carbon barrels contact the stainless slide at lugs (recall this is where Peter modified Browning designs get almost all lock up/contact--not the muzzle or rails), aft of muzzle (smiley wear), and barrel hood. None of that causes anything but contact wear.
Design issues are more important to me than metal type. P226 torques hard on the under rail, 92 hits the block hard, CZ includes multiple take down levers in the Sport because they break/Shadow breaks frames, old design tanfoglio broke slides, etc.
In the end, nitride penetrating metal treatment/hardening makes all thinks somewhat equal in form for a user for whatever you can measure as "better" experience. ie, whatever is "better" about another steel doesn't matter much after nitride on carbon steel.
I think that nitride makes carbon equal in qualities to ss is the answer to the OP question. Once nitrided, the carbon steel lost the carbon steel properties all around on the outside--no benefit any longer. And nitrided stainless somewhat or entirely removes the benefits of stainless.
A non nitrided carbon steel might have a person's opinion of being better, but bluing alone just isn't worth exterior rusting worries.
