Probably neither. Of course it all depends on the key schema and the data in the table, but you probably want to create an Global Secondary Index for your most frequently used queries.

Having said that; performing scans is highly discouraged, especially when working with large volumes of data. So if you know the primary key of the items you're interested in, go for BatchGetItems over doing a scan.
