I have worked with both for several years and the tets as a whole does have the stronger scapes and more substance. They also tend to have more vibrant color than the dips. I have found that the dips as a whole multiply faster here. I do not care for most of the tet spiders and ufs because of the added substance making them stiff and lifeless. The dip ufs and spiders do a lot more twisting and curling, making them more interesting in the garden. To me as a hybidizer there is enough difference that I only do tet round flowers and dip spiders and ufs. There are pros and cons with both, and some great daylilies from both sides. One other thing I have found over the years, dips are less likely to get crown rot which is a big plus for me.
