Moving from Razer Kraken V2 Pro to Blackshark V2

Hello, I have a few questions to the new Blackshark V2. I got it today and it is of course a lot different than my previous headset. Should I keep the THX Spatial Audio-Option on "Auto"? Does that mean that all games with THX Audio compability will have THX and all the other games have normal Stereo audio?, Or do you prefer the "Manual" option, where you can decide which programs will have different Sound?. I hope it is just me that I have to get comfy with the new headset sound since playing as example Rocket League was very weird to me when I switched to THX(and that is because RL isn't supported by THX if I am correct). RL will give me the Stereo-Sound and all the other programs that have THX Support will have THX-Sound automatically?
