No problem. So grapheneOS will definitely prioritize security more than the others. But ultimately, it still relies on hardware that, by its very nature, cannot be trusted. Similarly, even the developers at grapheneOS can make mistakes. Therefore, you should generally view such systems as compromised and not trust them blindly. Then there are also methods like uXDT, where devices communicate with each other via sound (a frequency we cannot hear), and so on. Thats the reason I call it honeypotOS.
