In general, that's nonsense. There are certainly languages which are comparatively close, so that it is hard to tell, and where different weightings can lead to different results. That doesn't mean it is like this for every comparison. For instance, the comparison between Java and Scala certainly doesn't belong to this group, just like comparing PHP with many other languages also leads to a clear outcome. But honestly, I don't care. There are also people claiming that there is no "objective superiority" in cases like "evolution vs. intelligent design", "6000yo universe vs. billions of years", "software patents vs. no software patents", "no contraception/abortion vs. women's rights". Right reaction is to laugh and move on.
