Poll: Best Companion (2005-2011)

Companions are an essential ingredient of Doctor Who, but which one since 2005 deserves to be crowned the best? You can only pick one, so choose carefully!

Note: The poll only counts multi-story companions, it does not include one-offs like Wilf and Lady Christina. They will have their own separate poll.

Note 2: Adam officially becomes a companion in Dalek; he carries that role until The Long Game (2 stories). Wilf, although in more episodes only became an actual companion in The End of Time (1 story, two parts).
