Test suites are not reflection complete! https://sdrinf.com/reflection-completeness -essentially, the moment a set of testing data gets significant traction, it becomes a target to optimize for.

Instead, I strongly recommend to put together a list of "control questions" of your own, that covers the general, and specific use cases you're interested in. Specifically, I'd recommend adding questions on topics you have high degree of expertise on; and topics where you can figure out what "expert" answer actually looks like; then run it against the available models by yourself.
