More interesting? Hardly.
RJDiogenes, the fact is superhero comics have as main and support characters alphas (think alphas from Brave new world): larger than life, innovative, gifted, etc. There's a very good reason for that - reading about such alphas is why people read superhero comics in the first place.
Alfred, if only a standard butler, would be strictly beta - competent at his job, but that's it. And that would be boring/frustrating to read about AKA the comics would not be read.
