Basic features are lacking. Roaming control: stop asking me if I want to use operator or Google Voice for every call because I'm roaming, a simple toggle should be implemented since so many plans include roaming now. RCS: supposedly coming since 2017 yet Google disses Apple for not playing nice. Integrations: the phone and messages apps should be able to connect directly with Google Voice so I can use the apps seamlessly. Enterprise users who want two apps can have them too.
