It was a bit of a later season for me here in Utah, zone 7. Of the approximately 20 varieties I grew, some were real standouts. For the small sizes, we loved Brad's atomic grape, and pink bumblebee as well as our old go-to, sun sugar. For the black tomatoes, black from tula was the big winner for production. For the reds, 1884 as always won on taste but could be more productive. But hands down, my overall winner due to earliness for size, flavor, and productivity is the yellow tomato, azoychka. I got well over 100 good sized tomatoes from one plant of azoychka. It can be variable in size, but it's crazy productive, and really quite early for a good size tomato.
