I am sure different people would have different answers to this question. It
is kind of difficult to know when it is *best* to use one over the other.
Maybe this video will help.

An abstract class enables you to create an object that has some of the
implementation in place but forces the derived class to implement certain
methods or propeties in a way that suits their own interpretation.

An interface enforces the contract that specifies the method signatures and
properties that must be provided but does not, and indeed cannot, provide
any implementation code.
