I can't speak for anyone but myself here, and I'm not contesting you--My 2cents is this: I like Martha more than Rose for two primary reasons. 1-I think Freema is the better actress. 2-Rose always peeved me with her treatment of Mickey. She was supposed to have been his girlfriend, and yet she'd flirt/be with any guy who took her fancy. I just saw Rose as amoral in that way, and I'm sure not many others saw Rose that way. Plus...Rose just bugged me. So my preference of Martha over Rose isn't out of snobbery, or belief that she's better than Rose because she's more clever, it's because of the characters themselves.

Personally, I never thought Martha should replace Rose in the Doctor's heart, but she should have more respect from him than what she got. There were times during the third season that I felt he dissed her and her feelings too harshly, putting her into situations that showed he had a total disregard for what Martha would have to go through in regards to her feelings for him. I never thought he was obligated to return Martha's feelings, but he certainly could have shown more respect for them at times. Hopefully that won't be the case this season, but honestly--I fear that when Rose comes back, Martha (and Donna too, most likely) will suffer some serious neglect and be given a 'place' behind Rose that I'll most likely see as unfair and unwarranted. Thanks for letting me share my opinions.
