I like Craig LeHoullier's approach: “To my palate, the most distinctive tomato flavor characteristics are tartness compared with sweetness, flavor fullness compared with blandness, and complexity compared with simplicity.”
The descriptions in his book "Epic Tomatoes" incorporate two quality ranges: Tart-Balanced-Sweet and Mild-Moderate-Intense.
P.S. The post that started this thread did not attempt to define "good taste", it was just an attempt to begin a list of tomatoes worth consideration for growing.
