You've hit up on the great divide between gardeners and hybridizers. Hybridizers generally want the latest, greatest, most expensive to create newer latest, greatest. Many times the latest greatest may not be "garden tested" in that no one knows how they perform in a wide variety of locations.
Garden varieties have stood the test of time and have proven themselves hardy and worthy in a garden setting in a wide variety of locations. Most of the "garden varieties" were once latest,greatest and many are award winning cultivars. The daylilies in your gardens that you love and enjoy have earned their right to be in your garden. Newest, latest, greatest cultivars have not yet earned that right, but they are tempting!
