Companion would have to be Sarah Jane Smith.
The Fourth Doctor (Tom Baker) and Sarah Jane Smith.
I also really liked:
The First Doctor (William Hartnell), Susan, Ian and Barbara
The Second Doctor (Patrick Troughton), Jaime and Victoria
The Third Doctor (Jon Pertwee) and Jo
The Seventh Doctor (Sylvester McCoy) and Ace
The Eleventh Doctor (Matt Smith) and Amy
My favourite incarnation is 8 - I know the TV movie wasn't great but he was a brilliant Doctor in it and the 8th Doctor is just fantastic in the audio dramas!
My favourite companion is probably either Jamie or Ace.
I actually have two favourite Doctors and two favourite companions.
Doctors: David Tennant and Matt Smith.
Companions: Sarah Jane Smith and Clara Oswald.
I can't decide between the two Doctors and companions I have chosen who is my favourite, because they all bring something fresh and unique to the Doctor and companion roles that they play.
Favourite incarnation is 11
Companion is Amy
My top favourite companions include Ace McShane and Jamie McCrimmon. My top favourite doctors are also 7 (Sylvester McCoy) and 2 (Patrick Troughton) so that works out perfectly for me.
Doctor Whooves and Assistant ;)
I mean Tom Baker and K-9
Tom Baker & Sarah Jane.
4th Doctor (Tom Baker), and Leela of the Sevateem (Louise Jameson)

11th Doctor and I love Amy and Rory. Peter Capaldi will be up there pretty quickly I'm sure.
