Well, 'City of Death' is often regarded as one of the best. It has a great blend of humor, mystery, and time - travel elements. The setting in Paris is also very charming. 'The Girl in the Fireplace' is another top story. The relationship between the Doctor and Reinette was beautifully portrayed, and the time - jumping aspect added a lot of intrigue. Also, 'Heaven Sent' is amazing. The Doctor's solo journey in the castle, facing his fears over and over again, was a very powerful and emotional story.
The 'Blink' episode is often considered one of the best. It has a unique and creepy concept that keeps you on the edge of your seat.
Well, for me, 'Blink' is definitely one of the best. The concept of the Weeping Angels is so creepy and unique. Also, 'The Day of the Doctor' is amazing because of the multiple Doctors coming together. Another one could be 'Human Nature / The Family of Blood', which has a deep emotional core.
Well, these stories are popular mainly due to their ability to create a sense of wonder. They take viewers to different times and places, both in history and in fictional universes.

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.
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.
