Sid Caesar can not be compared to the Saturday Night Live style of comedy because each is distinct and relates to what humor was/is in its own time.

SNL has strengths in that it has alot of history doing a certain kind of quality of comedy. It is like a good recipe, such as the recipe for Coca Cola, being just enough slapstick, raciness, and lewd jokes. Sid Caesar differs in that his approach is considered person centric, whereas SNL is better due to being City Centric.
