ADO ODBC vs dbExpress ODBC

Hello,
    I need to create a new database application that connects to a Sybase
SQL Anywhere 6 database.
I have to use ODBC to reach the database (because the DB server may change)
but I was wondering which one, between  ADO and DBExpress would give me more
performance when accessing a database via ODBC...

Anyone has made the comparison?

Thank you
Stefano
