NFL by far!
The AFL and NFL merged before the start of the 1970 season.
The NFL began in 1920 and the AFL began in 1960. The two leagues merged in 1970.

Well im not sure how, but NFL stands for National Football League. There used to be the AFL (American Football League) but the NFL and AFL merged.
The Dolphins joined the NFL when the AFL-NFL merger took place prior to the 1970 season. The Dolphins first season in the AFL was 1966 and were a member of the AFL East Division from 1966-1969.
AFL only played in four Super Bowls and were 2-2 other than that it has all been NFL. In 1970 AFL became the AFC and have won 19 and lost 22. NFL/NFC 23 - AFL/AFC 21
