I recall that there's a gene largely responsible for the sensation of bitterness, and it's related to why some people really hate brussels sprouts and other brassicas.
Naturally, not everyone is going to agree on what tastes good or even unique. Some people like sweeter tomatoes more than tart ones. Some prefer more earthy flavors. I think there's a variation of a saying in every culture about the visual aspect of food - "eating with your eyes first." That's partly why we have so many different looking tomatoes even if they don't necessarily taste very different from one another.
Still, I'm surprised that Tormato and Carolyn both agree on Prue! Now I want to try it...
