Boneyard and stay close as possible to your year model. The only issues IMO with used, original doors are two damage areas - the non-bushed hole at top of top hinge and bottom of bottom hinge, and chance of damage around the lock cylinder where people like to jam a screwdriver under to nail the lock pawl. It's a tricky area to repair well, so if it's not original paint, I'd be looking at it very hard to be sure it isn't loaded up with bondo right there.
Aftermarket body parts are always a gamble and something as important as how a door fits, I wouldn't even bother chancing it.
