The yellow fleshed taste about the same only a little different. Some people say they like them better. Some say they are sweeter. IDK, but they taste good to me. My daughter's friend's mother bought one the other day and spent nearly $8 for it. My daughter gave her three of them.
Sky here is something you might like to try growing. Its a Cherokee Purple tomato. Its an heirloom and first recorded around 1890. This is what the Indians used to grow and a Cherokee indian gave some seed to some fella around 1890. From the size you can see its a big tomato and is a type of Beefsteak tomato. It will produce continuously till frost and will get over eight foot tall if you tend to it but you have to train it since the tomatoes are so large they can break the vine.
Growing heirlooms here is difficult due to the tobacco virus so my three experimental plants were grafts and they seem to be doing well. The flavor is a lot different than regular tomatoes as they are not as tart and they are super juicy and are very fleshy.
