Independent (but not unrelated to your comment above) they also have life experiences that she does not have, and can offer her a different perspective. Xander hasn't really experienced much in life that Buffy hasn't - so the character doesn't have as much to add or standing to be a "challenger" to her even if that was intended as his role.
She cannot have a discussion with Xander about their group that is independent of their personal history fighting together. As a writer, it's harder to add to the story that way.
