LQ9 Vs Yaris Coils

Heyo, will be looking at upgrading the RB26 coils in future. Just wondering if anyone knows what is better between the LQ9 (LS Truck) coils and Yaris coils?

Being on the RB they will be mounted in the valley so will be exposed to a reasonable amount of heat.

I haven't used the Yaris coils but had great success with the LQ9's

Have you thought about going for a direct replacement like Splitfire coils or something like that?

All are the same price, can get bolt on kits for both Yaris and LQ9 coils for just over $500 (using tested second hand coils) compared to $5-600 for new split fires or $3-400 second hand
