I like cupcakes, and although I also like fairy cakes, I think the bigger (and different recipe) cupcake has advantages.
They keep better than fairy cakes.
As they are bigger, you can decorate them rather more lavishly, which is lovely for parties. It is also quite easy to buy small sugar ornaments or rice-paper decorations to put on each one.
One of my children, 40 years ago, asked for his birthday cake to be small individual cakes, each with a candle 'so everyone doesn't stare at me'. I found the cupcake recipe to be easier than fairy cakes. We then found that children like to take their individual cake home, instead of a crumbly slice, and it became a family tradition, carried on with his children. It also came into its own since Covid, with each child at an outdoor party having their own cake.
As for being bigger, you can cut them in 2 much more easily than fairy cakes.
