Answer 1

Memory usage and speed aren't the considerations that matter. You would not be able to measure a difference either way.

I think enums should be preferred when they apply, because the emphasize the fact that the chosen values go together and comprise a closed set. Readability is improved a great deal, too. Code using enums is more self-documenting than stray int values scattered throughout your code.

Prefer enums.
