[AccessD] ADP vs. MDB for SQL 2000

I am trying to convince a client that's rebuilding a DOS based system with
SQL Server 2000 and Access XP that the .adp format is superior to the .mdb
format for working with SQL Server back ends.  Does anyone have any articles
or any "objective" materials that I could show to them? (Another developer
has them convinced that the .mdb format is the way to go)

Thanks,
