Martha was the worst companion of the rebooted series. She started off OK in her very first episode and quickly degenerated into this soppy companion who would whine all the time about being in love with the doctor.
On the other hand I expected the worst from Donna Noble but she turned out to be fantastic.
My favourite companion though is still Ace. She attacked a Dalek with a baseball bat. I wanted my own backpack full of Nitro 9 when I was young. Although I also like Elizabeth Shaw but she got replaced by Jo Grant so the doctor could explain stuff as exposition.
