As far as I understand enum and #define I prefer to use enum since it is a data structure and the list of possible values that an enum can host defined at one place. If In case of #define for n number of statement you have write but in case of enum only at one place you can edit and it reflects its values wherever it is being used.
Debugging is also easy in case of enum. Another advantage of enum is during the run time its variable can get different values based on logic which using MACRO it can't be achieved.
