Grew 10 varieties this year and no disease problems so will report on taste, crop/fruit size and a few cultural notes:
Brandywine: Excellent taste but small crop of very large fruit. Slow to start setting.
Black Russian: Very good taste slightly better crop than Brandywine, large fruit, slow to start setting.
Tamina: Average taste, average size, good crop, set early.
Core de Bue: Very good taste, good crop, large fruit, still flowering!
Sungold: Very sweet but powerful taste, amazing crop of orange coloured cherry-sized fruit, still flowering! Lots of splitting though.
Ferline: Average taste, average crop of average sized fruit.
Suncherry Premium: Excellent taste (not as sweet as Sungold), excellent crop of red cherry-sized fruit. Will be growing this instead of Gardeners Delight in the future.
Legend: Very good taste, good crop of large to very large fruit.
Cristal: Average taste, good crop of deeply coloured medium sized fruit.
Stupice: Unremarkable taste, good crop of medium sized fruit.
Hope the above proves useful to someone.
