Merging Datasets Based on Hierarchy

I have three datasets that include address points. These datasets are of varying levels of accuracy and extent. I would like to merge these to create one dataset and take the data from the most accurate dataset.

Each dataset has a unique address code field and there are duplicates between datasets; so essentially, how can I tell ArcGIS 10 to merge the three datasets and if there are duplicates, here is the hierarchy or order to take the data from, if available?
