Seems to me Microsoft office is still the dominant player.
That being said, excel itself is still more powerful than google sheets, but the collaborative nature of Gsuite beats the pants off of MS Office, online or native.
My last decade has been a mix, some o365, some GDocs. I do wish there was something opened that was nearly as good as Visio myself, rather than renting it as an add-on. diagrams.net/draw.io is pretty good for some things, but Visio has a lot of features that aren't even close. I haven't tried the web version of Visio lately, last I had it was only halfway decent for read-only, but apparently most features now work. So next time I need it in mac/linux it should be an option.
I reinstalled Wordpad. Wordpad is sufficient for most things (including opening and editing most simple word documents--though that may be because I created them myself with office 2007) and if I really need a word processor (styles, page layout, etc) then I also have LibreOffice. I didn't even consider an Office license when I rebuilt last.
FWIW Docs isn't bad, and slides is... useable, but sheets is a poor excel alternative.
- if you have GMail, people(esp engineering) use docs and 1-n people have Excel on top
- if you are all in on MS, then of course no one will use GDocs
Excel at this point is specialist software, like adobe photoshop. Everything else is 'good enough'.
