1- Andy Griffith
2- Don Knotts
3- Howard Mcnear (Floyd)
4- Jim Nabors (Gomer)
5- George Lindsey (Goober)
6 - Hal Smith (Otis)
7- Betty Lynn & Anita Coursalt ( Thelma Lou & Helen Crump)
8- Frances Bavier (Aunt Bee)
9- Howard Morris (Earnest T. Bass). High rank . Shame only appeared a handful of times.
10- Jack Burns (Warren) I'll take some heat for this one but I love his episodes and think he did a brilliant job at replacing Don Knotts.
11 The Darlings
12- The fungirls
13- Josie Lloyd ( Lydia Crosswaithe) Only in a few episodes but monumental classics
14- Ronny Howard
15- Charles Thompson- (Asa, Doc Roberts)
16 Alan Melvin. Was in numerous but not enough episodes. Played as example escaped convict, roadside produce seller, martial arts episode and others. Each episode he was in was a classic with him making a huge contribution
17- Mabel Albertson- (Howard Sprague's mother)
18- Jack Dodson ( Howard Sprague)
19 - Hope Somers (Clara Edwards)
20- Alberta Nelson (Flora & others) Had true comedic talent & fit in well. Wish she appears more.
21- Paul Hartman (Emmit) Likeable.

I'd swap the fun girls and Warren.

Probably Burns' best episode was the sleepwalking one.

I'd also find a higher ranking for Miss Lydia. She should have been on more episodes. They could have made her Goober's girl.

I also agree they could have used Howard Morris more.
