On our charts the VOR is also 1700' for cat D with IAS less than 185kt, staying inside a fixed distance from the SES or GSE.
On the ILS chart, we also have 2860 annotated for Cat D ias > 185kt. For less than 185kt, you get referred to a circling minima chart which allows 1700' provided you stay inside a fixed distance again.
So no advantage to the VOR...
