Haha, have you actually had polished wheels? I've had both, the polished ones were a PITA.. spent an hour a week with metal polish just polishing the oxidation away (and it comes right back after 2 days).
Chrome just needed to be washed and dried.
I can substantiate this. Maintenance wise, chrome is a lot better than polished wheels. My polished wheels show water spots, light scratches, and dust a lot more than chrome.
