Easy one for me because i'm an old Cunia fan. In his day, Cunia had a lot of the answers. Since I have used both, I would say they breed similar in many ways. Cunia was larger framed, but that was in demand then. Both bulls could sire some plain cattle, and both could sire a really fancy one now and then. Both seem to sire better heifers than bulls, but that is just my opinion. Today, Cunia has a more lasting influence, but that may change. I like Cunia.
