If it were me, I'd check the action and bore to see all is OK. All things equal, I would then check the Ser. numbers to see if either is new enough for the barrel program. If neither/both are elligible for the program, then its "buyer's choice", but if only one is elligible for the barrel program, then I would get that one.
OR
Just get the one that "trips YOUR trigger" and forget about all the other stuff. Either way, I don't think you can go wrong, at those prices.
