Paying for G-Suite is no guarantee your files won’t suddenly go missing with no backups: https://news.ycombinator.com/item?id=17115643

I pay for G-Suite for a side-project I inherited (I use Office 365 as my daily-driver) and while there is human support available, they don’t make it easy to get to. With Office 365 the phone support contact details are 2 clicks away from any screen.
