Since the time that the series has been going on, there are many doctors who have been cast on the show. Each doctor has their own characteristics and so they have differences also. As the show has been running for years and it is a long time so there are many who have been on the cast and have performed the role of the doctor. It cannot be avoided then that people will compare the characters that have been performed by the different and plenty actors.
People have their own preferences but we have known a list that was made of the worst doctor and going to the best doctor. It is not the blame completely for the actor but it can be because of the character that they made him do. His actions, his customs and other things that were created for the episodes. Some of the worst on the list are Sylvester McCoy, Colin Baker, Paul, and John Hurt. According to the list, John Hurt is better than Sylvester McCoy.
Other actors are Matt Smith which is the favorite of my cousin but not the only one though. More list of the doctors includes William Hartnell, Patrick Troughton, Peter Davidson, Jon Pertwee and Tom Baker. All of this names in the last paragraph are considered better than the previous paragraph. The list still includes Christopher Ecclestone as the third best doctor. The second is Peter Capaldi and the one who is on top of the list is David Tennant.
