Perhaps it would help to taboo "symmetry", or at least to say what kind of... uhm, mapping... do we really expect here. Just some way to play with words, or something useful? How specifically useful?

Saying "humans : better = paperclips maximizers : more clippy" would be a correct answer in a test of verbal skills. Just be careful not to add a wrong connotation there.

Because saying "...therefore 'better' and 'more clippy' are just two different ways of being better, for two different species" would be a nonsense, exactly like saying "...therefore 'more clippy' and 'better' are just two different ways of being more clippy, for two different species". No, being better is not a homo sapiens way to produce the most paperclips. And being more clippy is not a paperclip maximizer way to produce the most happiness (even for the paperclip maximizers).
