I guess that’s true, although we could possibly split that camp into two sides: the folks who believe that Play Store sandboxing is going to be more functional, and the folks who prefer microG are willing to accept the issues that come along with it.
To be fair on either side of that debate, getting a phone that comes with /e/OS installed from the factory is going to be easier than flashing GrapheneOS on a Pixel or LineageOS with microG on another device.
