I have only watched the re-booted series but I like Martha Jones the best.

My favorite Doctors so far have been David Tennant and Matt Smith.

Really brilliant the way the show was written for ever changing characters.

Perhaps showing my age, but K-9 was my favorite Dr Who companion ... and maybe Leela then Martha then, well now, I favor the stunning in my eyes Alex, er, River Song.

I will admit that the theme of Gillan in her different ages (the start of the crack in the wall episodes which are still creeping in even though the Pandorica has been sealed again) is s stroke of genius, and the little girl who plays the younger version has done a good job in that part and even resembles Gillan!
