You would use War Bear because Hasbro Twin Horn is very rare and expensive. It is simply not an option for some people. War Bear seems to be the next best thing for a defensive zombie, even in left spin, because you can still use Saucer and it's still pinched well, even though it points in the wrong direction. Takara Twin Horn would be better for stamina, but also expensive and also pretty easy to KO.
I, and like everyone else I know of, use(s) Customize Grip Base for defensive zombies and Defense Grip Base 2 or Customize Bearing Base for stamina zombies
