According to some metrics, Hendrix may have the edge in popularity. For example, he has sold more albums worldwide than Van Halen, and his music is often cited as being more influential. Additionally, Hendrix was ranked number one in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time," while Van Halen was ranked number eight.
However, Van Halen also has a strong claim to popularity. He is one of the best-selling rock musicians of all time, and his music is still widely listened to today. Additionally, Van Halen was inducted into the Rock and Roll Hall of Fame in 2007, while Hendrix was inducted in 1992.
Ultimately, the question of who is more popular between Hendrix and Van Halen is subjective. Both guitarists have made significant contributions to rock music, and both enjoy a wide fan base.
