The Best companion for the 10th Doctor

Who could forget Rose Tyler with her complete devotion to the Doctor. Martha Jones who's only wish was for the  Doctor to like her, but the best companion for the Doctor would have to be Donna Noble. A redhead with a feisty attitude did not let anybody push her around. Whether she went back in time, or faced an alien race, there was no messing with her. As the Doctor Donna she most single handily destroyed almost the entire Dalek race. She also stopped the Doctor from himself. That is why she was the best companion of the 10th Doctor. Sadly she forgot everything that she accomplished.
