Greddy RS vs Greddy RZ bov

[Nerf]

About a year ago I found that my HKS SSQV (first gen) was going bad. To replace it, I bought a Greddy RS BOV (new, but mad cheap!) while it was in the process of being discontinued. Unfortunately, it came from the factory with a small leak that causes issues under light throttle. When attempting to loosen the nut and tighten the bolt a little it turned out that it was also somewhat stripped from the factory, and with a few small turns of mine it became completely stripped. I'm not ready to swear off Greddy altogether yet because I understand that things happen. I know that some other people have experienced the same and similar experiences with their RS too. So I'm wondering if anyone has any good or bad experiences with their Type-RZ bov? I'm running a s15 sr w/ intake, full exhaust / elbow (oem manifold), increased boost to 12PSI on stock turbo, and some other minor stuff. I plan to get to, but not exceed around 330-350whp. Is there an optimal BOV for a stock-ish setup that performs any better than others? I'm just looking to get something I won't have to worry about next time so I don't waste more money.

tldr: My Greddy RS sucked. Is the RZ engineered better? And is there a "best" bov for a stockish sr setup with bolt-ons?
