She is broken because of the snap, which wouldn't happen in the 2014 universe. In her universe Iron Man doesn't sacrifice himself, Captain America doesn't decide to spend the rest of his life in another timeline, and Hawkeye isn't destroyed by guilt at the death of a version of that her she has no experience of. I don't see why she would feel more affinity for this messed up universe than the one she currently inhabits, where she is appreciated for who she is – and not as a second-rate replacement for a bunch of cowardly "heroes", who can't live with a version of her not being in their lives.
Gamora's situation is different, because she is the last of her species and her "family" is killed in Endgame, so she has no existing ties. And she never fell in love with Quill and had none of the experiences that constituted their relationship in the first place. So she cannot replace the person that Quill lost. It would be like if your parents died but you went into a parallel universe where your parents never had you, and brought them back to this universe to live with you. Would it be getting your parents back? Or living with a bunch of strangers?
