Sweet Jenny is a variety I don’t hear talked about much, but it’s possibly the best muscadine I’ve ever eaten, and between what I’ve grown myself and tasted from friends’ vines I’ve tasted well over a dozen named varieties. Sweet Jenny is super tasty and sweet and has really good size. In my experience, it’s not nearly as productive as some of the self-fertile varieties, but I’ve mostly been happy enough with the productivity.
Darlene in my experience is close to Sweet Jenny in taste, similar in productivity, too, but the fruits aren’t as big, and I lose a noticeable percentage to rot issues, which haven’t been a problem with Sweet Jenny (although I planted the two varieties in two very different locations.)
I think Hunt is a loser, at least for fresh eating. It’s fairly productive and free of problems, and its size is pretty good, but the sweetness is lacking. Maybe it would be good for some kind of processing, though.
