It doesn't really matter. The difference is miniscule. Enums are also better because someone else reading your code (or yourself) will know what everything is.
It's in the same layout:
DATA1, DATA2, DATA3.
And especially with only 3 values, it's not different. Everyone has their habbits, but a lot of people think the wrong thing.

Mapping the enum could potentially save memory because it won't loop every time.
