Corsair RM650x vs EVGA 650/750 G2/G3/P2

[CampinP]

As title suggests, I am looking for a power supply, max 165mm. The EVGA G3 line up is brand new so I don't know if they're much better than the G2 and therefore much better than the Corsair?
But the G3 is about the same price as the P2 variant so I wonder again which one is better.

Looking for the quietest one and best in build quality (so not necessarily efficiency), thanks!

The RMX Corsair and the EVGA G3 made by Super Flower for are both top of the line models , would be a great choices.

Both models are very quiet , I own the RM850x and 3 EVGA G2 and 1 P2.

I'm aware of that, I'm just wondering if the new G3 series has any major improvements over the G2/RM. On top of that if the P2 is better than G3 (efficiency aside)
