GM is good enough for lounge access on international SkyTeam (and certain other partner) itineraries, so I would ask whether the higher upgrade priority that PM would get over GM is worth it. OTOH, PMs get one choice benefit, which can be four RUCs, as well as free change/cancel/redeposit on award tickets.
