i got a ss apron front sink after i saw rmkitchens. i too love mine. i also find i wipe it down the least of all my stainless appliances. we have had ours installed since late summer and so far, no scratches either.
i have used vinegar/water mix and it does work well. i also use weinman's stainless steel cleaner (spray in a silver bottle) and i think it's the best i've found. it does seem to protect the surface from smudges/fingerprints.
i say go for it! here a pic if you need a little push!
