Which are your favorite Crape Myrtle varieties and why?

Already have Zuni, Sioux, and Dynamite Red. But may have To replace one of two of my Zunis after a really bad winter, in terms of sustained cold rather than record cold.--(May give it another week or so as I am coastal, and seasons tend to be delayed.) Looking for one that I can keep more vertical than sprawling out too much. Really like Zuni (color and form), so may just get another one of these. Thanks in advance.
