A stickler for quality, Ozzie was adamant that his program look different from the inferior kinescope products dominating the television schedule, and he hired Academy Award winner William C. Mellor to shoot the program in the finest 35mm film stock. With preliminary editing complete, Nelson would then rent a Los Angeles theater and screen two or three episodes back-to-back for audiences in order to gauge the placement and intensity of the laugh track cues.

imo, he was a super over-achiever so yes I also think he was a perfectionist. Also steady, fair, and reliable. It seems that those who worked on the show had nothing but nice things to say about Ozzie.
