If I have to rate, I would rate Dilip Kumar as No#1, Dharmendra as No#2 and DevAnand as no#3. I have watched many movies and as per the film and role selection, the character played, dialogue delivery, emotions portrayed, acting and over-all performance, I have given my rating. There may be different people who would give a different ranking but for me, this is what I feel.
I do not understand why the writer has picked up these 3 names as there are many other actors and would have been better for the reader to provide their best from the lot. I liked Rajesh Khanna, Manoj Kumar, Shashi Kapoor, Shammi Kapoor, Sanjeev Kumar, Raaj Kumar to name some.
Ranking an actor cannot be a foolproof as it depends upon the story, the character played, overall performance, etc. In one movie I may like one actor but in another, I am like a different actor due to the character and it will keep on changing. It would be better if the writer provides a gauge like the name of the 2-3 movies to rank them which be used as a common standard by all.
