Yes, this comparison is in broad aggregate, so there is lots of fungibility in terms of price for quantity as well as quality. Broadly speaking though, there are so many different people with so many different requirements for thickness, texture, and some intangible sense of "feel" that one must do their own comparison. Few are likely just to decide based on price and will have some sort of gut reaction of one format over another, much less reactions over quality, quantity, and price. This also doesn't get into how each type of paper works well or doesn't with one's favorite pencils and pens. If all of these things were easily and directly comparable, then there wouldn't be so many subs on Reddit dedicated to stationery.

There is also a reasonably well known brand name tax on many of the higher end notebook brand names, so attempting to compare things on that front is terrifically fraught to begin with. Even Exacompta's Bristol cards face this in addition to import/distribution "taxes" which spreads the cost of 100 100x150mm cards anywhere from $4.00 to over $14.00 per pack. Personally I love the feel of their cards, but am disappointed that they're neither a standard 4 x 6 inches nor A5, but some separate custom size all their own, and almost no purveyor ever mentions this fact.
