Mashed
In addition to being the clearly more delicious option, there is also a more accessible version of said option for those who do not have the time to make mashed potatoes from scratch. Thus instant mashed potatoes, although a fair to middling imitation of its namesake, mean that everyone can enjoy lovely, garlicky, buttery mashed potatoes even if they are very busy or are unable to lift a masher!
There is not an instant version of boiled potatoes. Also they are gross.
