@hambone I found that book excerpt when I was looking for which pawpaw variety to fill the last available spot in my backyard. I had heard about many varieties being standouts, like Susquehanna and Shenandoah, but couldn’t decide on one. I saw Englands Orchards was selling seeds from Jerry Lehman’s numbered crosses. The crosses were just sweeping the Ohio Pawpaw Festival it seemed, so I searched “250-39” to find out more and that’s one of the web results. For reference, here is a picture of 250-39: https://www.facebook.com/ohiopawpawfestival/photos/a.597508676962496/597508696962494/?type=3&theater
I agree that there isn’t much info on taste test results. I have personally tasted Mango, Allegheny, KSU Atwood, Rappahannock, Summer Delight, and quite a bit of fruit from wild trees here in North Carolina. My sample size is small, but the best I have tasted of that lot is Summer Delight, a cross of Sunflower and Overleese by Cliff England. The flavor was mild yet complex, had a thick texture, and seemed to have no off flavors or bitterness even at a later stage of ripening.
Here are a few results from Ohio I have found:

The 2018 winners were: 275-56 (Benny’s Delight), 250-30, and Green Gem…and the winner for size was 275-48 (Lehman’s Delight)
And here are some of the winners you can put together from the England’s Orchard page: http://www.nuttrees.net/pawpaw_seeds.html
It would be worth contacting the festival to see if they could share the list of winners from all the different years.
