A programming language could be measured by the efficiency of the language. Or the cross-platform nature of it. So a language can be good in some circumstances but not as good in others.
If we took javascript and forced you to write “let’s end this statement right now please” instead of the standard semi-colon, it would an objectively worse language. This proves it is at least possible to have one language be “better” than another language.
There are plenty of examples of "objectively worse" programming language designs, i.e. ones that have have no silver lining. For instance, Javascript's and PHP's illogical "truthiness" concepts.
Whether being objectively bad means anything in real life is another question.
