I agree with
@Squid509 in general, it adds some latency and complexity to the system. Unless you have a specific use case for a vrx, but my reasons for that are for external monitor situations that don't involve goggles.
That being said, I love my hdzero box pro and 2 (divimath). considering getting an external analog module, but the built in ones are really good. the box pro and 2 both have "low latency" hdmi in (total latency will still depend on the cable, vrx, etc).
