Niether... both MOM and AOSW both have full complete packs..no damage to them...
but if you mean which exhibit has the ESB helmet with the ROTJ suit, then that would be the AOSW...
I think the only time the pack was damaged in the ROTJ:SE was when Don Bies wore it with the girls and when he was added walking behind Jabba, he was played by another ILM employee on a soundstage with the regular pack.
I don't think there were very good movie shots of the SE pack. I do believe the AOSW costume was used for the SE shots, so I would probably use AOSW for your paint scheme.
