My point was you can't do a random sampling of alternators for various models of cars then conclude that Ford Parts rebuilt alternators are better or worse than aftermarket. In most cases, the rectifier and regulation assembly is buried inside the aluminum case and hidden from view. You would need to compare a particular aftermarket reman alternator for a particular application to the original and to the Ford parts reman unit. I am willing to bet that Ford Parts is selling an alternator unit that is rebuilt by an aftermarket outfit, not by Ford OE manufacturing. Furthermore, the OE alternators are not so impressive from a lifecycle perspective. I've had similar luck with aftermarket rebuilds.
