we "believe" something is better or 'feel' that something is better without real justification
I think people are having a hard time getting passed the matching tobacco brand to pipe brand issue when it appears, maybe, you are really asking about psychological influence in general. If so, I offer this:
This is not tobacco but, I was reviewing an offer for a relatively low chateau of $25/bottle. Their pitch, basically, started with "the chateau lies near Le Pin". To fill everyone in on Le Pin, it is most often in the thousands of dollars per bottle range. The psychology being, if it that near a chateau of that caliber, it must be a great bargain for the that price.
This is akin to saying "Fiats are a spectacularly great bargain because the factory is near the Ferrari factory". What seemed reasonable with the wine now sounds ridiculous with the cars. (Let's please not start a conversation about terrior. Skill in production is a major factor in quality.)
Back to pipes and tobacco. Dunhill dark flake is rather fantastic. So, psychologically, all of their other blends must be too? Seeing what has happened since the end of Dunhill this seems to be correct psychologically but not necessarily logically or in actuality.
So we can compare one Dunhill blend with another and get away with it psychologically speaking, similarly to how we can compare a low-end Bordeaux with a high-end Bordeaux but it doesn't seem to work with matching blends to pipes by brand somewhat similarly to comparing a particular car to another.
Not a perfect analogy, or even a good one, but I think it functions to illustrate the point.
