A poor misguided soul over-equipped with access to media published a blasphemous treatise suggesting a mayonnaise taxonomy in which Duke's is not atop the hierarchy. This shameless heretic goes so far as to assemble a team of "taste testers" who declare Hellman's to be the best tasting mayo by a wide margin.
One take on this is the obvious -- it is stab at satire, revealing the all-to-common budding journalist's desire to pose as this generation's Swift. After all some of the comments on Duke's taste include "vinegary kick" and an afertaste--qualities long associated with Hellman's and never with Duke's. Of course this could be mere incompentence--the inability to keep the various samples straight. They did note one of Duke's strong points, a robust texture that results in tomato sandwiches with adequate mayo which will not simply squirt out the tomato slices all over your plate.
And this brings us to another incredible point, this author made his first tomato sandwich with a single slice of tomato. Perhaps this correlates with the erudite affectation associated with heirloom this and that, as if heirloom is something obtained by means other than death of a loved one, and even if that were possible that this so-called heirloom retained any of its original value. Regardless, one who actually makes a tomato sandwich with only one slice, no matter how thick that slice, is suspect as a judge of anything southern, and there is little more southern than the tomato sandwich.
At the end of the day, what was true remains true: if you're not spreading Duke's, you're spreading crap.
