The Tomb of the Cybermen is often considered one of the best. It has a great plot and showcases Troughton's acting skills well.
For some, The Mind Robber is the top choice. It's highly imaginative and takes the viewers on a unique and thrilling adventure. Troughton's performance in it is top-notch.
The 'The War Games' is also considered among the best. This story is quite significant as it led to the Doctor's first regeneration. It has an elaborate and engaging plot with various alien species involved in a complex 'war game' scenario. It's a long story but keeps you hooked throughout with its twists and turns.
A significant number of fans also consider 'The Enemy of the World' to be a great Patrick Troughton story. It has a really interesting premise where the Doctor looks exactly like an evil dictator. The story is full of political intrigue and adventure, and Troughton gets to show off his acting chops by playing two very different versions of the same face.
Well, 'The Girl in the Fireplace' is also a top contender. It has a wonderful, almost fairytale - like quality to it. The relationship between the Doctor and Reinette is beautifully developed, and the setting across different time periods adds a lot of charm and intrigue to the story.
A great Doctor Who story often has an interesting villain. For example, the Daleks are classic villains that can make a story really exciting. When they are involved, there's always a sense of danger.
The 'Web of Fear' is also considered a great 'lost' story. It was missing episodes for a long time. It had a really cool concept of the Yeti in the London Underground. The story was full of mystery and suspense, with the Doctor trying to figure out what the Yeti were up to and how to stop them. It was a classic 'Doctor Who' adventure with a great atmosphere.
For me, 'Blink' is the best. It's got a brilliant time-travel concept and those creepy Weeping Angels. The story is super engaging and keeps you on the edge of your seat.
Well, it's subjective. However, 'The Day of the Doctor' is often praised for its epic scale and the reunion of multiple Doctors. It had great special effects and emotional depth.
For me, 'The Abominable Snowmen' stands out. The story had a mysterious and spooky atmosphere that would have been captivating on screen.
For me, the 'Davros' arcs were outstanding. They brought back a classic villain and had some intense moments.
The Time War arc is often considered one of the best. It had high stakes, intense drama, and really explored the Doctor's character.
