Any paid Google service with an SLA is perfectly fine.

The choice between Microsoft 365 and Google Workspace should mostly be a matter of taste.

Google Workspace is very straightforward and largely offers better finish and UX. I personally dislike Google's material design and find myself confused by it, but most people seem fine with it.

The UI isn't always good and the web versions suck, but everything is also very flexible and intended to scale to almost everything the IT dept of a Fortune 500 companies with tricky compliancy requirements might require to control a fleet of Windows machines.
