If I were you, I wouldn't make my dicision just on where the disc are made. Got a friend who upon doing tons of research on the web and he would only buy discs made in Japan, I gave him some of my Sony disc which are made in Taiwan and now he would only buy Sony's!!!
Just go out and get few brands, be it made in Japan or Taiwan and use them on your burner and you would know which ones are the best for your burner......
I think there is no such thing as best disc for every burner out there, just some disc just works better than the other....oh...don't forget to get those with "limited" lifetime warranty, and basically stick with Hitachi/Maxell,Verbatim/Mitsubishi,Fuji,Sony and their co-branded oems and you will be fine.....
