I also tried Outlook and Zoho. I prefer Fastmail over those two, because it's really simple (may be a con for some) and has a very snappy UI.
you might even say...it's //fast//
(I'm kidding, but having a fast UI really is part of the DNA of the company, said as a user since the original days)
Zoho Mail -- GMail
Zoho Writer -- Google Docs
Zoho Show -- Google Slides
Zoho Sheet -- Google Sheets
Zoho Workdrive -- Google Drive
Zoho Cliq -- Microsoft Teams (not sure what's google counterpart)
What I like in Zoho Mail:
1. Practical mailing use cases like sharing/commenting over a mail is possible.
2. Privacy focussed.
In Zoho Writer:
1. Has more business usecases solved than Gdocs - like pdf templates, sign integrations and mail merge integrations.
2. Tools are arranged better than a standard top toolbar.
I moved my email for all my domains to Fastmail.
I did not use any of their the other suite / apps so no loss there. I never found the Google Apps platform very usable over Actual apps like MS Office, or even LibreOffice. The web versions always seemed very limited. (even web version of MS Office)
I joined Google Apps in ca. 2006, was grandfathered and I still use the service today (Google Workspace)
Switching is really painful, though, because I am quite attached to the ecosystem and it would require substantial work to recreate it from bits and pieces.
I had a look at the console but did not find the limitation either (it is certainly somewhere)
I don't trust them to keep that though so I moved my email anyway
It’s annoying that they charge extra for the downloadable version considering their web apps are so bad.
If Google Workspaces wasn't around and I were building a new start up, not really sure what I'd want to pick. Fastmail is fine for my personal use, but with a company I'd want more features to control things. And then all the office apps. Possibly Libreoffice and a self hosted Nextcloud. Not really something I would want to be hand holding though.
I don't know how I'd replace gvoice, but email is easy.
I've been happy with the results.
To the nearest ledge high enough to guarantee a fatal fall from. Or maybe the nearest downed power line or water-filled bathtub (into which i could drop a plugged-in toaster).
It is very featureful, but the interface continually gets in my way.
Fastmail if you just need email, CalDAV, CardDAV, and light WebDAV.
I use (and/or administer) both daily and like them for different reasons.
