If I buy this car it will definitely be the auto.

Likely the road noise is coming from a higher final gear size in the manual. Because the auto and manuals have completely different gear ratios, the final gear will usually be specific to the last gear in the transmission. That way the RPMs are nearly identical for both transmissions at cruising speeds... It's a good chance that the final gear in the AT is smaller (thus less noise) to make up for the larger last gear in the transmission, while the MT will have a smaller 6th gear which would require the diff to be larger.
