Oh my, no comparison. The Hybrid will run much cooler and have less noise. It's also more pricey for that reason.
But Hybrid one doesn't have overclocking potential like G1 Gaming SOC.Standard PCB vs Custom PCB
I've seen reviews of G1 SOC with OC up to 1555. The reviews for Hybrid OC are just starting to come out. Guru got it to 1514MHz while other have claimed 1600MHz potential without any proof yet.
