I think the original Quantum Competition design is coming from Nosram. Before buying Nosram, LRP had only the brick size IPC speedos. I don't see how Nosram would be lower quality than LRP when both companies uses the same lines for production
Basically all LRP stuff has its Nosram equivalent:
For example brushless motors:
- LRP: 4Star
- Nosram: Storm -

HIGH END brushed motor:
- LRP Fusion Phase 4.1
- Xtreme Modified 2

Saying that LRP is higher quality than Nosram is the same like saying Peak V2 is worse than Orion V2
