There are some awesome "hyper-realist" artists out there[0], [1]. It can be argued that they are even better than cameras, as there is an element of emotional interpretation, and the artist can do things like play with the context.
But there are many that would argue that this isn't necessarily "art," as art is an interpretation of an emotional experience, as opposed to simple documentation.
Piacsso's Portrait of Igor Stravinsky[2] is considered one of the better portraits out there, and it's not really much to look at, if you are looking for realism, but it will sell for a heck of a lot more than some of the hyper-realistic works in the previous links.
Art is a story, not just a document, and that story includes many components, including the artist's own story.
I know that one of my favorite artists, is Roger Dean[3], who is not particularly realistic. I have never really been a fan of Boris Vallejo[4], who is probably a much more skilled draftsman.
I'd say that the question "Is one artist better than another?" is almost meaningless.
