I was at the Sheraton Parsippany twice last month and both stays were fine. I was upgraded to a club level room both times (no suite). The rooms are renovated and have the new Sheraton beds but the real plus for me was the jetted soaker tubs (which I think are standard in club floor rooms).

I’ve never been to the Westin but there are several negative threads about it. I’d defiantly go back to the Sheraton but the standard rates there are pretty steep.
