I have to say that while Donna was insufferable in the beginning, she really grew on you. Becomes one of the better companions as you keep watching.

Martha... well her run gave us Blink. And she was barely in it, which was good. And I guess the Shakespeare ep wasn't horrid. Completely dull as a companion otherwise I fear. Doctor needed someone who'd be his friend, not be pining over him, and Martha wasn't it.
