Can't advise you which one to buy but, be careful of the terminology. Genuine may be Genuine Honda but that does not mean it is 'original' to that bike as fitted by Honda. I'm not saying it is in this case as I don't know but they could both be the same guard, from the same manufacturer but the Genuine one will be in Honda wrapping and the pattern one, wrapping with no Honda written on it. Also, not necessarily with this part but as yours is a USA model bike, check the listings carefully. Someone will be along soon to advise you.
