I am not sure what hyperwhite consists of, but a lot of guys really like the Silverstars. They will be my next pick (I have tried some lesser bulbs - only one kind was really good and the rest, um, not so much).
make sure your lenses are clean & clear on both sides. If not there are threads on how to clean them, just search. I highly recommend silverstars. They are considerably brighter and whiter and last just as long as a standard bulb. They don't burn up real quick like APC or the generic hyperwhites.
