Led Zeppelin and it's even a contest.
I like Nirvana. They were the last great rock band but Led Zeppelin is on another planet in comparison.
Nirvana made a few catchy songs, they put out one okay album and were big for 3 years max. They made decent, not great music, and were a flash in a pan.
They're best known for their emo singer killing himself, which says enough lol.
Led Zeppelin are among the greatest and most influential bands of all time. They made timeless music and consistently for 12 years. The band members are all virtuosos and among the greatest in their field.
Cobain isn't fit to spit shin Page and Plant's shoes. He was mediocre guitarist and singer and songwriter. The other Nirvana members are all bang average too. Bonham with foot on his bass drum has more talent than all Nirvana members combined and that's not an exaggeration.
