In the range of media, opinions will always vary...
Some media manufacturers, and genuine partner rebrands, are almost universally judged to be good (Taiyo Yuden springs to mind here), and should deliver good results unless your drive really does not like them.
Some, and this varies with drive, are judged to be crap (Princo?).
Some (Ritek codes) can be excessively variable.
Then you get CMC, the paradox - from average to very bad in CD-R, but their DVD media is well written by some drives, next to useless in others - some would put them at the first level in quality, the majority would probably put them in the socond tier, and if your drive doesn't like CMC, then you put them in the 3rd or bottom tier.
