In my opinion, you cannot go bad with the M&P Sport, it doesnt scratch or show wear any worse than any other AR, in fact the Barrel scratches less easily than any I have found. If you are on a limited budget (I was) you cannot go wrong with a Sport, you will find when you buy it that you will want to dress it up but shoot it as it is a bit before you start dressing it up so you know what direction you want to go. I like the fit and finish better than the windham in my opnion and I know the accuracy is better.
