Chromed or 'lined' AR barrels - or not

Last week, the forum offered some good advice on the purchase of a 5.56 Lower for a provisional or future build.

The Smith & Wesson AR15 Sport I previously purchased has a proprietary Melonite lining/coating instead of a chrome liner.

So, on a purchased barrel, what are benefits or a chrome coating? Is it a wear issue, since chrome is harder, or is it resistance to corrosion from rust or powder/primer components? It's not my intent to shoot rounds with corrosive components if I can avoid it.

What advice?
