The testing I saw a few years back showed that it was most likely that the hands gave a reroll on learning and there is no testing to indicate that is different on the +1. That said, I HQ'd my SAM AF head just cause, if you have the mats, why not, but you're better off HQ'ing the body which has actual benefits.
