[AccessD] Search in AC2007 and SQL-Server

What I'm trying to do is compare Access with SQL Server and Dotnet with SQL
Server for a potential client.
The big differences vs. dotnet are:

1) object orientation vs. procedural
2) source code versioning
3) rich number of GUI controls
4) secure deployment (EXE, DLL, etc)

There is no significant issues regarding data retrieval speed when talking
stored procedures and ADO, correct ?
IOW, the Access app should be just as fast.
