SRAM does not "make chains".. they are produced with SRAM branding by another company.
if it were my bike, i'd be busy trying to identify the differences in the two chains... and frankly, i rarely use any SRAM drivetrain parts, like their derailleurs.. or shifters. Too clunky and just plan odd. Many like them.
i have installed several of their branded chains... they are slightly wider than KMC chains, as per my measurements. I have never noted a difference in "noise" from either KMC or SRAM.
i DO use products from companies SRAM bought with big bank loans. Avid and RockShox.
