Google Workspace vs Office 365 for Thunderbird

I manage IT for a small org (10 users) where we currently use thunderbird with email services provided by a website hosting company. We'd like to move to either Google Workspace or Office 365 for email. Considerations [1] Our needs are simple, email and contacts. One user uses folders extensively. [2] I have some exposure to using google workspace with thunderbird, and I'd say that's pretty smooth. [3] I have no experience with Office 365. [4] No one wants to move to Outlook from Thunderbird [5] We subscribe to Office 365, so google workspace would be a new cost In researching how o365 works with Thunderbird, my conclusion is that Microsoft is still quite capable of making it less than smooth. I'd very much appreciate input from those with exposure to o365, and even more anyone that can compare the two services from the Thunderbird perspective.
