Well, that's interesting. I couldn't really identify any of mine to a
specific control object though. 

So, do you think there's no appreciable difference between the two then --
as a performance issue? It seems to me, that pure SQL should always be
faster, regardless of how Access communicates it to Jet.

Same:
Behind the scenes Access creates a fixed query for the literal string.
You can see the hidden fixed query which is prefixed by a "~" using
following code in a form module:
    Dim dbs As DAO.Database, qdf As DAO.QueryDef
    Set dbs = CurrentDb
    For Each qdf In dbs.QueryDefs
        Debug.Print qdf.Name
    Next qdf

A literal SQL string or a fixed query?
