You're assuming a certain sort of perspectivalism: the only reasons X could be better than Y is that, from someone's pov, some language has X. This is kinda insane. People can give reasons X is better than Y on grounds of various theoretical virtues of X -- that has nothing to do with a preference for any language. Here's an example virute: Behaviour should be consistent unless specialised. When specialised it should be obvious which specialisation is chosen. (Violation: basically all of js' operators).
