I'm a huge Doctor Who fan, and Jon Pertwee is my second favourite Doctor after Tom Baker. I particularly enjoyed his stories with The Master, and Roger Delgado is the best Master in my opinion. Such a tragedy when he died. By now, I daresay you've watched classics like Spearhead from Space, Inferno, Terror of the Autons, The Daemons, and The Green Death. I love the Brigadier too. :)

I reckon you'll love the Tom Baker stories. There are many classics, especially in the first three series, produced by Philip Hinchcliffe (the best producer the series ever had, as far as I'm concerned). Also, Tom Baker's early series feature best ever companion Sarah Jane Smith (Elisabeth Sladen). Genesis of the Daleks, Terror of the Zygons, Pyramids of Mars, The Brain of Morbius, The Seeds of Doom, The Deadly Assassin, The Robots of Death, The Talons of Weng Chiang... I could go on (and I have, sorry). :)
