I had Isis Candy Cherry last year, 3 plants everyone was different the the other. My biggest plant was the best the others I didn't really eat many of. Black Cherry is the bomb diggity, those were so awesome, everyone who tried them absolutely loved them. I will probably always have them somewhere in my garden.
Black from Tula was also very good, though I had lots of splitting. But the splitting was rampant throughout my garden, all in all a very great tomato.
I will be trying Ark Traveler this year I hear they love the heat and are great producers.
Arkansas Traveler - reliable plant in my SoCal hot and dry garden. Sets fruit in high heat. Really big thick foliage. Taste is very good.
Fireworks - super early cluster producer. Takes cool and gloomy weather well. Tall plant but not dense of leaf. Excellent taste for such an early variety. Already have three of these in the ground for April/May tomatoes.
Stupice - also super early variety. Similar behavior to Fireworks. I have better results with Stupice in spring than in fall, but that speaks more of my climate than the tomato itself. Taste is good. Prefer Fireworks taste but find Stupice to be resilient and worth planting as well.
I have grown Black From Tula and Black Cherry but never a big fan of either. Both have excellent flavor but for me Black Krim outperforms both in my garden and I'm just not a fan of cherries.
