My family have grown the same tomato for more than 20 years. It is a hybrid called Terrific, but last year we could find any started plants nor could I find the seed. We grew Rutgers and Celebrity, and they were awful. So I spent much of last year looking for different varieties to try and bought some Cherokee Purples and Opalka's due to several rave reviews. Well I found the Terrific seed this year and ordered them as my family were still unconvinced to change and we found started plants too. So they planted 30 Terrific's and I planted 4 Cherokee Purples, 4 Opalka's, and 4 Chadwick Cherry. Hands down the Cherokee Purple are the best tomato I've ever tasted, they are very large, but they got blight really quick. Next year I'll plant them a little differently to help with this because they are a wonder tomato in my opinion (which is limited).
The Opalka's are a very tasty tomato, but they are a winner for canning. Very productive, meaty tomato. Some of the tomatoes weighted over 2 pounds and it has the blight but is still producing and growing new vines and taking over the Cherokee Purple tomato cages. Easy to peel and can. Another winner in my opinion and I will be growing more of these and giving them more space to keep producing next year.
The Chadwick's did not do well at first until I discovered the drainage problem, but they have taken off and are producing tons of cherry tomatoes. I love canning them in my salsa because they add a tartness that I like. They are extremely productive, but the best tasting cherry to me is still the Husk Cherry Red by Bonnie. They are more sweet.
The 30 tomatoes in the big garden have produced tons of tomatoes (Terrific's). We have well over 200 quarts canned and are giving away the 2nd crops to friends and other family members. If you can get them, they are a good producing plant and have good tomatoes, but they are very juicy. The opalkas are a good canning tomato because I don't need to cook them down to make Italian style sauce so much, so I get more yields off my efforts.
So it depends on what you're looking for. I will be planting more opalkas for canning and cherokee purples for eating. No more Terrific's for me. Next year I want to try Sun sugar or Sun gold cherries, because of things I've read online.
