After 2008, almost everyone became familiar with the Avengers. They made superhero films a billion-dollar business. However, the Avengers were not that powerful in the comic books. Their human flaws are what make them compelling characters. Still, they are not the strongest team, not in the comics anyway. The Avengers come together to fight threats that one member could not stop, and they did not always succeed. If you really want to go there, the Avengers lost in Avengers: Infinity War. Many other comic book teams are stronger than the Avengers.
This is not to disparage the Avengers. They are a household name and have made a new generation of casual readers and fans. However, the Fantastic Four, Eternals, and even the Justice League are more powerful than the Avengers. Even the Ultimates, the modernized version of the Avengers in an alternate universe, are technically more powerful than the Avengers.
