Don't have that many roses, and Knock Outs are perfect for some people. However, I am not personally fond of them, either. They are nice for the 'hell' strips coming in and out of the shopping center. Our city is using them as drought-tolerant landscaping for medians and such. But they look kind of scabulous when all those blooms fade at once. (Yes, I made up that word, but it IS descriptive, isn't it?
) Besides, I tend to look for roses with few thorns and/or that are best as stand-alones or accents for combination plantings.
