As an "IT admin", it's not that I need convincing. It's that the rest of Googles "office" products are absolute amateur hour and support is non-existent.

Not quite sure about this. Gmail (both personal and company accounts) is IMO a great email client with loads of handy features, and I always felt Google Docs/Sheets/Slides/Drawings were well put together. Are they the best in class? I guess it depends what you are looking for. Could Drive be faster? Yes, that would be nice. But "amateur hour" sounds like we are simply using different products.
I have used Microsoft Office for 20 years and Google Docs/Workspace for 15 years. I much prefer the Google suite over the Microsoft one. I prioritize quality of user experience, ease of use, performance, platform portability, freedom from constant intrusive software updates, and not messing with the built-in Emacs key bindings built into every Mac (Various MS Office programs inconsistently disable those key bindings). YMMV, esp with UI and UX, but for me there's no contest.
Regarding support, that is not an issue I have never needed it for Google, but occasionally have needed for MS Office. So I can see why if you are using Office you would value that.
