Most people grow sweet corn in their gardens, so they won't be growing these.

There are heirloom sweet corn varieties, but they have to be cooked in minutes/hours from harvesting to remain sweet.

As far as the starchy corn, you won't get a lot of flavor difference.

There is flavor difference in the starchy corns as well as texture difference! Obviously they all taste like corn but there's certainly variation.
