To credit them both, they always show up to a fight in shape and ready. They both take the sport very seriously, and any true fan should at least respect that about them, no doubt. But as far as beig a fan? I like Vitali. But Wlad? I never root for that motha****a!
I like Klitschkos because they are not trash talkers, they are always in shape, they are the best heavyweights in the world, they do not break the law, great skills, they speak, at least, four languages, etc.
