At the MSP I work at every single customer we have uses Azure AD. G Suite isn't a proper business e-mail solution for a business with any more than 3 users - Exchange and Azure AD are the gold standard for cloud based office for SMB.
Sorry, I know tons of highly effective organizations, large and small, that enjoy the benefits of using Workspace for email, calendaring, and the whole rest of the lot.
Back in 2007, I was supporting massive educational organizations, with hundreds of thousands of users, to move their entire email and calendaring operations to the then-called GSuite. That was 14 years ago.
Google created the cloud-based office solution. MS has been playing catch-up, trying to lovingly recreate the experience of managing an on-prem Windows/AD/Exchange stack for the metaverse equivalent of self flagellation.
Previous two companies (650 users, 250 users), were also gull G-Suite.
