I can add the following anecdotage and I will watch more closely this growing season: I have VdB EL (from Martin) and VdB (from UCD). Both are clearly VdBs in terms of leaf shape, fruit shape, fruit color etc. Both are potted but different in growth and fruiting habit. UCD is older, grows more vigorously, produces breba that it will hold, ripen, and taste good with cooperative weather. EL produces smaller fruit with a more compact, bursty type of sweetness - solo trumpet like whereas the UCD fruit are larger with a lingering look type of smooth sweetness - Sunday brunch jazz ensemble like. The EL produced more fruit earlier than the UCD. If I had to pick one, I choose VdB UCD Sunday Brunch style.
