Canines. They seem more agressive and dominant. I also think of them doing the frontal assault. Something about the canines are what makes them look so strong and like a work of art from nature. Felines feel to me like they run, hit, and hit the road.
Might seem confusing, but there isn't really other better reason to tell why I prefer Canines more. Maybe even cause up here in north, we don't have many wild cats.
