"Because the world is objectively real, of course some things are better than others, by any reasonable criteria."
Given a set of criteria with objective measures, one can objectively tell if something meets those criteria, or not, or whether it meets more of those criteria, or not. But words like better and good express emotional value judgements. It is, as far as I can tell, impossible to prove that my criteria for what makes something good is objectively better than yours.
E.g., I may think food A is better than food B because it is spicier. You may may think food A is worse than food B for the very same reason. How do you determine whose version of better really is?
