For Game and Video back-up's I'd go with a decent disk rather than risk jerky playback or incompatability.
Tuffdisk! No! Hahaha... Thing with them is, they could have three or four different overprinted brands/mid's just in a single spindle. You might get a good spindle of overprints, but it's a total lottery. For budget media they are also a tad overpriced methinks.
If you tell us your burner we may be able to suggest alternate budget to midrange media. So often though, buying cheap does not pay. Hey, we all wish it did...but...
EDIT: Generaly -r (or +r booktyped to dvd-rom) for console compatability. The speed of the disks you buy is not necessarily what you are compelled to burn them at, and 2-4x media is very rare these days. What make and model of drive do you have and what speeds does it burn at?
You should be fine with either 8x or 16x as long as you have at least an 8x burner. Consider burning your 16x media at 12x as it may give you a better burn. All media is different and burners are too. You have to either be very lucky, or do a bit of testing to find what combination of media and burnspeed works best with your burner.
