Best media for NEC 4550?

I’m about to get an NEC 4550 and wanted to know the best (reliable, good quality burns at rated speeds) media to use for it. I plan on only burning at rated speeds:

CD-R (Audio)
CD-R
CD-RW
DVD-R
DVD-RW
DVD+R
DVD+RW
DVD-RAM

Any help on deciding the best media to buy would be most appreciated.
