It handles related data. For example, if a feature class has attachments enabled and an additional related table, simply copying and pasting only the feature class will also copy over the relationship classes, attachments table, and the additional related table.
It provides you with a list of which datasets and related datasets are to be copied:
This list will also inform you beforehand of issues such as naming conflicts or domain differences (domain with the same name exists in source and target, but the domain values are different, for example). You can then abort the copy, fix these issues, and try again.
It provides progress bars during the paste operation.
