Little Rock or Memphis?

I am torn between Little Rock and Memphis -which one has the best BBQ? I am visiting Little Rock, and wanted to know which place has the best BBQ in town. Any suggestions on what places I should stop by?

H.B.'s, Whole Hog, Sim's, Corky's, Wright's, are popular. I have never been to Three Sam's at Mablevale, but it looks like it has a good reputation.
