If you have to ask, you wouldn't get it. J-3 Cubs have significantly better flying qualities than Champs, BTW. I've owned both.
And I don't get why people say Cubs are over priced. Over priced means priced higher than the market will bear. Cubs are priced the way they are because they fetch those prices.
AvWeb did a side-by-side a couple years back and it seemed to me from the description that the Aeronca was better in almost every way
