Troubleshooting Question

Want to determine the most accurate and fastest VBA coding to determine if a table exists?

I have the following two TableExists functions.  Which one you would use as to the best?  Which one is faster and more accurate?  Although the first one is faster I don't believe it to be truly accurate in only using the name of the objects when something is a query instead of a table.   And what would I need to do to change it to be more accurate or what else would you use below instead?  Cause I would like to have my own personal function to determine query, report, etc. and plan to take what you tell me and use that.  Thank you in advance:

Public Function TableExists(tblName As String) As Boolean

    If DCount("[Name]", "MSysObjects", "[Name] = '" & tblName & "'") = 1 Then

        TableExists = True
    End If

End Function

Public Function TableExists(ByVal sTName As String) As Boolean


  Dim sSQL As String
  Dim bValue As Boolean
  bValue = False
  Dim td As TableDef
  For Each td In CurrentDb.TableDefs
    If td.Name = sTName Then
      bValue = True
      Exit For
    End If
  Next td
  
  
  TableExists = bValue
  

  
End Function
