Technically speaking, there are limits and you cannot compare incomparable. You can find distinctions between two phenomena, a.k.a. inherent traits that make them different-by-definition from one another, but you cannot compare (liken, collate, contrast) them in any meaningful way. Like, what's the outcome of comparing "soft" with "warm"? And hence, comparing apples to apples are not pointless, quite contrary - they are comparable items and it makes total sense to compare them in the context of superiority by desirable value axes.
