I think you demonstrated that eggs taste different, but not better.
My 2 year old would only prefer to eat frozen chicken nuggets. That doesn’t mean they are superior to actual whole chicken.

It will depend on whether the whole chicken is chicken proper, or one reassembled from nuggets.
eggs are homogenous in nature, so a blind test between two eggs can reveal the superior quality of one type of homogenous product. Especially when it is an egg, which is entirely "natural"
a chicken nugget is not the same thing as whole chicken, because it has many chemicals, additives, flavouring agents, msg, organ meat, etc and is then battered or crumbed and deep fried before being packed. It also has a different texture altogether, and is eaten with the hands which children find easier than using cutlery.
compare a child tasting two different varieties of dark chocolate in comparison to a milk chocolate with caramel filling, or two varieties of whole milk to chocolate skim milk, et cetera.
Nuggets are mostly skin and cartilage, so maybe that preference stems from the nutritional needs of a growing child.
My kids prefer nuggets over the whole roast chicken my wife and I eat. The salt, MSG, and seasoning of the nuggets along with the fat from the oil tastes better to them. Sadly, nothing I say will convince them otherwise.
