A sealed class is "an extension of enum classes". They can exist in multiple instances that contain state while each enum constant exists only as a single instance.

Since, in your example, you don't need the values to be instantiated multiple times and they don't provide special behavior, enums should just be right for the use case.

sealed class vs enum when using associated type
