Well, they’re more like a band of Hans and Chewies. They lack that supreme moral center, zeal, and innocent purity (Luke, Leia, R2D2, C3PO). Gamora is sorta like Leia, but her ultimate goal is just to grt away and free.
And ultimately, the war they got involved in was just a small conflict within the context of the greater universe (where gods and monsters and superheroes are all fighting each other for their own piece of the pie). Sure, the stakes were high, but everything significant that happens in the comic book universes is world-ending, reality-shattering craziness.
In Star Wars, it’s just the Empire and some criminals who also work with the Empire vs. “everybody free and good”.
