The best media by far is from a company called tayo yuden. they actually manufacture i believe 80% or so of all cdr stock in the world. There is a grading scale for CDR's that dictates their bulk sales prices, so "A grade" CD's are kept by them to sell at a premium mostly to album mastering houses and recording studios. B-D Grade CDR's are usually sold to other compaines such as TDK, Sony, etc. the complication to this is that CD quality control can change from batch to batch, based on the success of the dye process and so forth. For burning personal CD's Tayo Yuden is a bit of overkill IMO, and can be difficult to consistently obtain. I find myself constantly changing CD brands based on sales personally, unless I am burning CD's to go to mastering, in which case I always have a pack of TY's on hand to get the best quality burn. If you're ever unsure of the quality of CD's that you're using, CD Analyzers are a wonderful thing. 🙂
