iceberg lettuce is, as you say, a sandwich lettuce, not a salad lettuce. It has a very clear crispy texture (as you say). Radicchio is only crispy in the center part. It was a revelation when I moved to california and had my first real salad. it was intensely bitter with nutty and other flavors. Later I found out that arugala, endive, radicchio, are all great when properly dressed with a good salad oil, but they definitely have wayyyyy more flavor. I'd be surprised if anybody could even really say what iceberg lettuce "tastes" like- to me it just tasts like crunchy water.
