Russ is correct: both kits come from the same mold.
I haven't seen either of them outside the box in many years. Other modelers report, however, that Revell Europe (which, apparently, is what the former Revell Germany officially calls itself now) has had some serious quality control problems with its big-scale sailing ship kits in recent years. There are disheartening reports of soft, overly-flexible plastic, warping, and incompletely- or defectively-molded parts. There are also reports that the recently-sold examples of the "American" version are in fact molded in China or Korea. That may imply a considerably higher standard in terms of plastic quality and overall quality control - or maybe not.
None of the above, I'm afraid, helps Rick much. If (gawd forbid) I were in the market for one of those kits at the moment, I'm not sure which one I'd pick. If possible, I'd take a careful look at it before spending money on it. Otherwise, I'd be strongly inclined to buy the one that cost least. I don't think there's any direct relationship between the quality of the kit and the price in this case. If I had the chance to get an old one, molded back in the sixties or seventies, for a reasonable price I'd be tempted to go that route.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
