I tasted some sparkling wines that to me were way better than Dom Perignon. And Pino Noir (forgot particular brand) I get for 20 Canadian pesos again tasted to me way better that some wine I bought for $120 to check why the fuck does it cost so much.
So yes I am pretty sure that some wine is objectively better than sulfuric acid but the rest is just a matter of individual taste. It does not matter that the tester can distinguish between 2 buttles of the same wine and tell the year it's been produced.

The thing about champagne is it produced using the traditional method [1]. As long as other sparkling wines are also made using the same method, they can be quite good. My favorite non-champagne sparkling wines are Crémants[2]. Much cheaper than champagne, but as good or better depending on your personal tastes
Créments tend to be much sweeter than Champagne, hardly comparable, not like I enjoy either.
To me, Champagne is basically a nostalgic drink at this stage.
