Mayonnaise and Miracle Whip are two totally different items with totally different tastes. I use them for different purposes. They happen to look similar but so do Marmite and chocolate frosting.
Marmite: Now that's an acquired taste! Used to work with a gal raised in Britain that put that on almost everything. I bought a small jar and wasn't able to use anywhere near half before it went off date.
Lots of stuff has Marmite-like yeast extract in it, but straight Marmite is powerful stuff.
Dukes is the stuff, no doubt. Miracle whip is, as someone said, a different thing altogether than mayo. I found the Kraft olive oil mayo similar to MW, useful on the same stuff, and half the calories.
