I agree with Andrei: Use an instance variable until you need it to do something special, and then convert it to a property.

In Python I tend to use methods directly, even though I think properties are clearer and I actively avoid calling getters/setters directly in Delphi. I just can't be bothered to write the extra line for some reason :). On the other hand, I never write getters/setters just for the sake of it. In your example I would not have a self._value, but a self.value which is accessed directly, since the getter and setter don't do anything special anyway. Now, if I had such code and needed to add some processing before accessing the variable, I might change it into a property and add the appropriate methods, so that the interface remains the same.
