You have received several good suggestions. And like with most things opinions and suggestions will vary. First remember taste impressions is different for each individual. And I feel you have to rate each tomato by it's class. That is use, shape, size and even color.
I'm in a semi arrid region which has experienced severe drought the last few years. We have high temps with high winds. So things get stressed here and what does well else where may flop here. So when reading my suggestions remember in your garden results can be better or worse. And taste like wise. What makes Vidalia onions taste like they do is the soil. I grow the very same varieties in my garden and although good they don't taste just like the ones grown in Vidalia.
Many that I like that do well are what I call the darks. Cherokee Purple RL and PL, Indian Stripe(good disease resistance) , True Black Brandywine(good disease resistance) and Black from Tula, Amazon Chocolate and Carbon are some of my favorites that do well.
Smaller dark would be Korney's Cross Good disease resistance. A very good tomato that can be used as an all around mater.
All around reds in the 4-7 ounce range two good ones are Glick's 18 Mennonite and Heinz 1439-Det
Larger reds I grow are Chapman, Neve's Azorean Red are some of the first to come to mind.
Money Makers is one in the plum size range that is disease resistant and produces heavy.
Hybrid Red slicer types I like are Goliath, Old Fashioned Goliath and Porterhouse.. Another that was a good slicer with average flavor is Jetsonic. The Goliath's have shown good resistance in the previous 7-8 years I've grown them but both went down this year. Jetsonic never blinked an eye.
Pinks I like are Todebusch Pink(PL with disease resistance, large 12 ounces up to 2 lbs) one of the few large maters that produce many for me. Picked around 12 and had anohter 15 or so on the vine at frost, Brandyboy(Hybrid with good disease reistance that I must grow every year(, Hege's German Pink, Caspian Pink to name a few.
Other colors
Kellogg's Breakfast- A large beefsteak type. In the 10-16 ounce range and a heavy producer. A must grow every year. Flavor in the top 3 I grow
Emerald Evergreen - Very good taste. This was the first year. Size was around 3-4 ounces but flavor as good as Cherokee Green.
Juane Flammee' - Plum size orange-golden tomato. Good disease resistance and a heavy producer every year. Great flavor.
I have tried the Brandywines here off and on for the last 8 years. I tried 8 different strains this year. I have yet to find one that will produce and that unbeatable taste has been elusive here. Again climate, soil and gardening practices make a lot of difference. True Black Brandywine is by far the best I've grown along with Brandyboy a hybrid version. I will try two new hybrid versions this next year.
If I was to raise a plant for one fruit it would be Lucky Cross. The best tasting tomato I've ever tasted.
I have an inventory of over 400 varieties so could name many more. These were just what came to mind first. And many of these are available only as
seeds. i have
seeds for most if not all if you want to start your own. Free if requested.
Dave glad to see you posting. May God Bless you. Jay
