Personally I use the second best rated disc media, Verbatim. Apparently, and this is from a while ago, Taiyo Yuden is the best, and the only place I've seen it is on Newegg. More expensive than most media, and I normally only buy discs when I really need them and when they are on sale.

Here's my source of the above info:

Turns out Taiyo Yuden and Verbatim may be one in the same.
