I've been buying what they call "Plum Tomatoes" and they are much better than anything else I can get here in Sweden. Technically I think they are Grape Tomatoes, as they are quite small.

These are reliably at least fairly good in the UK, too, along with cherry tomatoes (about the same size, but round). Plum tomatoes are a bit firmer and cherry tomatoes are a bit sweeter.

If you compare a typical Dutch tomato to a supersized watermelon type tomato from California, the Dutch tomatoes are ten times more flavorful.

Ten times zero, is still zero ;)

What do you mean by "supervised watermelon type tomatoes"? Are you referring to some of the the huge heirloom tomatoes? I find there yellow ones particularly flavorful. Much better than there Dutch stuff.

i live in Los Angeles, and most of the tomatoes i've found in supermarkets here are low in flavor.

OTOH, if I buy the $5-$6 per pound heirloom varieties, the flavor is better.

even better: tomatoes grown in people's backyards.

Best tomatoes I've ever had were indeed grown in a backyard. In volcanic soil.
