Ritek are often relabled ("Octron" is one example) and some of them are of poor quality, while some are good (but still not as good as Verbatim would I say, even thought the older [not orange-box] Verbatims were a bit better).
If you find original Tayos, then get it.
They are great!
Verbatim 8x PearlWhite are one of the best, from all Verbatim which were produced (they are relabled Tayos).
All Verbatim should work, but it also depends on your Burner, its write-strategy, its Firmware, burning-speed and so on...
