[Marvel/MCU] How powerful are the Guardians of the Galaxy compared to Earth's superheroes?

Reflecting on Civil War II got me thinking, how big of a threat are the Guardians to the Avengers (or the X-men in the comics)? I figure Drax and Gamora are similar to enhanced humans like Captain America and Winter Soldier, and Groot is at least as strong and impervious as Colossus. But are any of them analogous to a Hulk, a Thor, or even a fully-equipped Iron Man? I'm not really asking who would win in a fight (I know that is a different sub), but just a general idea of how powerful the characters are.

I'm talking specifically about the Guardians line-up from the first movie of Starlord, Groot, Drax, Gamora, and Rocket.  Examples/comparisons from both the movies and comics appreciated, especially if they are more powerful in one medium than the other.

EDIT: So far lots of great responses, but not seeing a lot on adult Groot, who I would assume has the most raw strength/durability (though it sounds like 616 Drax might have more from some of the comments.) Also, I believe in the comics he can replicate himself much faster than in the films.

Rocket's tech is far beyond Tony's. Remember he has a handheld (for a raccoon, even) device that was regenerating the Milano after it crashed.

One of the deleted scenes from GotG2 has Gamora lift and carry a gun as big as she is, so saying she's as strong as Cap is kind of an understatement. Drax is even stronger than her.
