I would say if you only have two bulbs and are running them on a IceCap then go with the Phillips as you can't use a VHO to full potential on a IceCap anyways. (and there are to many reports of people saying there is almost no difference between NO and VHO bulbs on a IceCap. If you are using a WH7 then go with with VHO as you can wire them to take advantage of the VHO bulbs.
I went from overdriven NO bulbs in my tank to "properly" driven VHO bulbs and there was a huge difference. The overdriven NO's looked like a night light compared to the VHOs running full power. Now I am running overdriven VHO but that is a different story
