Is there any reason not to use ADO and OLE db?

I’m just wondering since I’ve used these objects from navision (MDAC 2.1) and haven’t encounted any trouble yet.

Is there a true ADO driver for Navision, or are you using the ODBC driver via ADO (which is perfectly possible of course) ?! So far, the combination Navision Financials, ADO and Delphi didn’t give me any troubles at all ! But we won’t be seeing any speed increases as long as there isn’t a true ADO driver !
