What are they called, then? Since I took a job overseas over ten years ago, I haven't been in American grocery stores much. What's the "normal" variety called? I distinctly remember Roma being the cheapest, and also worst-tasting, variety, and learned to buy the "on the vine" style instead, but those are the only two that stuck in my memory. What is the one I'm forgetting about?

"Beefsteak" tomatoes are perhaps the most common (and the worst).

Roma have...some flavor. Campari (the ones on the vine) and cherry/grape tomatoes are better, but still mediocre.
