I have used the Osrams and the Phillips are better IMO on H7s, but not sure on H4s. I've used the Halfords sooperdooper bulbs and they are bloody good too- got a set on my VW T5 van in H4 and one on my bike.

I have the phillips in H7 in my Freelanderer and the Osram Rallye 65ws on my main beams as they are a more focused beam designed for main beams. Works bloody well...
