Is there any advantage in upgrading the bov. If all I wanted was noise I would vent the original to Atmospere. Is there any power gains??

There will be no power gain. In fact, another other BOV beside the OEM one will get rough idling and/or stalling.

Even blowing your stock BOV into the atmosphere will screw up your performance. Your car will inject extra fuel and not have any returning air to match it. Your A/F ratios will get all screwed up. It's best to just stay stock. Plus... you get better gas mileage.
