Zoho is great, if you only need email and basics. O365 and GSuite are still unmatched as a package though. Still think O365 is the best deal (for SMBs+), though it's a bit more.
It is worth noting one of the features you give up is any sense of security or privacy what so ever. Not in the "omg google is spying on me" paranoia sense, but in the real Zoho hires the absolute cheapest developers in the world to build everything sense.
I've literally stopped reporting bugs to them because they can't grasp the flaws I am trying to point out.
Sev0 security issues aren't secret just because people who mean well don't talk about them, any sufficiently high valued target is going to have well funded threat actors working to find vulnerabilities. By publicly disclosing the issues, you let other customers know their data is threatened, and then customers can work together to force vendors to fix issues.
A little bit of PR buzz and customer complaints can get a handful of issues fixed, but this is a bit more systemic.
And Meet is amazing. The only video conferencing system I've used that actually works reliably. I recently moved from a company using Zoom to one using Meet and the difference is insane. Makes a step difference to the quality of remote work.
I presume they can do it because Google owns their own global network and they can use high QoS on it for Meet data.
I also find Google Sheets to be inferior to Excel, and we have Office licenses for myself and a few others that use spreadsheets.
The only thing I think is good with Workspace is Gmail and Calendar. Everything else is kind of meh.
I used to have Google Hangouts/Meet problems all the time, but it was fine, I've never cared for Zoom in general. Google's slide deck program is fine, but that's largely just because...who cares about slides? Most people aren't paying much attention to them, and they are just meeting filler.
I do prefer Gmail's interface to Outlook's though. Outlook tries to do too much. It's definitely better than it used to be, but there are some very crucial annoyances.
Works beautifully
I do miss Gmail, but it's easy to workaround it
