Would there be some good alternatives that could replace the word "easy" in this context?

In this context, "easier" has been used to mean "effortlessly," "less difficult," and "straightforwardly." Thus, we can use all of these alternatives. The most natural, however, would be "way easier" or "way less difficult" since it's talking about the ease with which an action is done. Ex: It's easier to learn how to swim if you take swimming lessons. Ex: It's less difficult to learn how to swim if you take swimming lessons.
