River Song is the best companion on Doctor Who

("I’d also like to say that although I’ve been watching this site for a while, this is my first time participating, so please let me know in the comments if I’m doing something wrong. Anyway, on to the debate." Don't worry, you're doing great!)Thank you for all of your arguments, and I'm sorry to have taken so long to reply, school life has not let up on me.1. Rose is made to be relatable to new viewers. Rose is a normal person working a low wage job. She has a mom and a boyfriend. She is a completely normal person, and that is attractive to new viewers. She has no idea of the universe around her and, like the Average Joe, probably could care less. She is swept up into the doctor's world in the blink of an eye and, like anyone, would be confused. She is us. She needs explanations, and that is part of what makes her attractive to the viewer.2. Rose's life is less obvious.Right off the bat, the episode after we meet her, *SPOILER FOR THOSE NOT FAR IN THE SHOW* River dies. Her story ends, just like that, before it really begins. We know the signs of when she will die, as she brought them up, and we know when we will see her last. That kills any tension around her or the 11th doctor when action ramps up, as we know nothing fatal will happen to them until it is her time.*SPOILER OVER*Now for my counterpoints:" 1. River is the Doctor’s equal. When the Doctor first meets River Song, she succeeds in handcuffing him against his will and taking his place as a sacrifice. The Doctor has met his match. From that moment on, he recognizes that River doesn’t need sheltering, something he never did with Rose, whom he often tried to send away to safety. Rose Tyler can be described as the Doctor’s “helper” of sorts. She follows the Doctor around and picks up the slack, often requiring long explanations to understand what’s going on. In contrast, River understands the Doctor so well that she is able to explain his thought process to everyone else. River is also able to fly the TARDIS instinctively , unlike Rose , and mastered that skill to the point where she is better at it than the Doctor. "This was addressed in my first point, but I'll say it again: Rose is made to be relatable to the viewer. River is amazing, don't get me wrong, but she is not relatable. She is alien to the viewer, and at first sight is extremely unrelatable to us. That is her first flaw as a character."2. Rose is possessive.Traveling in the TARDIS, Rose often gets jealous of anyone who the Doctor pays attention to. [It’s very clear that she doesn’t want to share him with anyone, and can be very rude to people whom she feels are a threat. She immediately deems Sarah Jane a rival , resents Mickey for deciding to tag along, and is jealous of Martha. River, however, is shown to be entirely neutral to the Doctor’s companions." I will concede that Rose is possessive, but note that she does grow up in Journey's End and The Stolen Earth. With the Doctor still around (and before what happens later in Journey's End) she isn't visibly jealous of any of the companions.3. Her tangled up timeline is realistic.Rose’s timeline is entirely synchronized with the Doctor’s (save for their brief encounter in The End of Time), which is rather unrealistic for a man who travels through time and space. River Song is unique in that his first encounter with her is her last. She is the first recurring character with an entirely non-linear timeline, and it surrounds her with unanswered questions. River doesn’t need anything explained to her; she knows it already. For the first time on Doctor Who, a companion knows more than the Doctor, and little by little, we learn more of her mysterious past. I touch on this on part of my second point, but I concede the untouched remainder of your statement. "4. She has catchphrasesAlthough Rose was the Doctor’s companion for two solid seasons, she doesn’t develop any recurring catchphrases that would automatically identify her. River, however, has several phrases she uses with the Doctor, namely “Spoilers,” and “Hello, Sweetie.” Having a unique signature makes her memorable in a way that Rose cannot be."If you see the phrase "Bad Wolf" you are reminded of Rose Tyler. That is her signature, and it is written across time itself. River's catchphrases are brilliant, but nothing can compare to Bad Wolf and Rose.
