If the focus is DVDs, I don't know.
If it's CDs, then maybe. I begun to dislike Ritek, but it's only based on one brand (TDK), and I suppose the quality may vary based on client requirements (different materials, different QA?).
After the supply of quality TDK CD-Rs stopped around here, they started bringing cheapo TDKs made by Ritek that were rather bad.
About Princo CD-R, I'm yet to find out about the long term, but the short term seems fine. In fact, better than Verbatim/Mitsubishi and Sony which I thought should be good. (The writer is Sony CRX230ED, and I find it funny that Sony media doesn't work well with a Sony drive).
