The sugarin corn starts to turn to starch as soon as it is picked.
Jubilee is a regular Hybrid sweet,has a good old corny flavour but loses it's sweetness quickly once off the stalk,it freezes well. For fresh eating needs to be cooked as soon as it is picked.
Butterscotch is a sugar enhanced corn, sweeter than Jubilee and sugar enhancing gene enables it to keep better off the stalk for a few days.
They each do different things actually. The first has the old fashioned taste, the second is sweeter, it comes down to a personal preference. Mine would be the Butterscotch.
