It doesn’t matter if it’s Rao’s or Victoria or Classico, whoever likes the Aldi sauce likes it.
But no, it’s not just the sodium. The fat content is also different (which is a pretty big differentiator as Rao’s is heavier on oil than most). And an ingredient list being the same doesn’t make the product the same — what kind of tomatoes, for starters? Which olive oil? What proportions of onion and garlic? If none of this mattered, we wouldn’t have people seeking out san marzanos or specific brands of olive oil and so on. And at a sharply lower price point, you can be certain the ingredients used are different. You can also bottle at the same plant and not be bottling the same product or the same recipe.
It’s just one person’s conjecture (“ I immediately recognized the bouquet and flavor profile” — but that person does not usually use Rao’s – they happened upon it because Walmart substituted it for… Classico).
In the comments, someone else says the suppliers of the same Aldi label differ regionally, and a third person says it’s an exact match for Victoria not Rao’s, to which the OP responds “fair enough”.
So… no.
