Just a couple of thoughts...
Jeffersonville is the best "value" course in the state, dollar for dollar. It's the "Mark Twain GC" of PA.
It's also more forgiving for the beginner, because it's tough to lose a ball out there, save for a couple of creeks, an instance of OB or two, and the pond on 18.
Matt will think it's too short, and for his game, he may be right.
Lederach is something very different and special and even though there are more opportunities to lose a ball, there is a lot of forgiveness and width built in. It's just not as lenient as Jeff (which is a "core routing), simply because the housing considerations dictate the routing to the edges (and wetlands, et.al.) of the property in some cases. It's also a more rolling property than Jeff, which is both good and bad for purposes of architecture...good for the ability to create more interesting, captivating, and stimulating holes, and bad because of sidehill kicks, etc., which have been mentioned as potential lost balls into the gunk.
I'd conclude by saying that while Jeff is the sort of course anyone can play and enjoy again and again, Lederach seems to me to be like the Beatles "White Album"; experimental, daring, varied, sometimes flawed, restricted in practice but not in imagination, but overall an exercise in mental stimulation and drawing from many, many fathers for inspiration yet somehow also uniquely original.
