Try....Finally..end Query

Which is best and why ?
1.
   try
     CredSearch := TCredSearch.Create(Self);
     CredSearch.ShowModal;
  finally
      CredSearch.Release;
  end;

2.
 try
     CredSearch := TCredSearch.Create(Self);
     CredSearch.ShowModal;
  finally
     CredSearch.Free;
     CredSearch := Nil;
  end;

Thanks,

is all you need to free the form.  Setting it to nil is to avoid having to
check Assigned prior to your create statement.

This line should be before the "try".
