I think that the real answer is "the one I belong to." Because to begin with, in order to determine if a person is a Christian or not, you need to define what it means to be a Christian. It has to be more than just believing in Jesus Christ and accepting him as your savior, because the JWs do that. However, the JWs have a raft of beliefs that are different from mainstream Christianity and they use those to explain why they are the only true Christians. So it requires more than just recognizing Jesus as your savior. Or even as your LORD, since most Christian denominations recognize Jesus as god, and yet insist that the others are not real Christians.
They need to present a list of reasons why they are the only real one and everyone else falls short. And that requires interpretation of scripture and justification for that interpretation. And while it provides a small amount of amusement to watch competing denominations battle over which interpretation of a sloppily-written book is the correct and proper one, it also gets tedious. It's like watching people argue over the best way to change the oil on a tricycle.

"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
