If you want an ORM, use EF.
If you want rich data mapping tooling (designers, etc.) use EF.
If you want to write your objects back to the database, use EF (accessors are read-only).
If you're already using DAAB, and want to remove repetitive data reader loops with lots of really simple left = right assignments to construct your data objects, accessors are great.
Accessors are a deliberately simple solution aimed at 75%.
My personal opinion is, if you're writing new code, prefer to go with EF, especially if you're working with a domain model. If you've got existing code that already uses DAAB, then the accessors can really clean up your reads out of the database.
