You get _nothing_ for improving things that already exist. As a result you get four different messaging apps, and not a single one that doesn't suck, and a bunch of stagnating, seemingly abandoned products. The reason is simple: people who are smart enough to understand the rules of the game move on immediately after launch to the next big thing.
Having said that, I still prefer GSuite to Office. Microsoft has set the bar very low indeed.
I can't help but think they are rewarding the right thing -- new shiny things may have the best ability to bring stragglers onto google the platform.
Unfortunately, it leads to the feeling that google just dabbles in things.
That all said, I think the bigger problem is a willingness to put out things that don't meet a high standard. Ex: the new web GMail launched while slower than the older one. This was done to get new features out to users faster, but it doesn't feel that great from a product excellence POV. There's no Steve Jobs figure telling us the Pixel 4 doesn't look great and as a consequence we should go back to the drawing board. It's more like there's a set of market survey results and the phone was made to check those boxes.
Depends upon which pieces. You can pry Excel from my cold, dead hands; OneNote is still an amazing piece of software that is getting pretty sweet updates; Outlook by itself is pretty solid for 80% of use cases, with fast iOS/Android apps; everything can be tweaked to your liking with some VBA scripting.
Onedrive also gives you more free space vs. Google Drive when signing up, I believe, though creating Google Docs / Sheets / Slides don't contribute to GDrive storage space - which was the deciding factor for us.
And yes, my wife is an accountant, so Excel is mandatory for her. She _can_ do most of what she does in Sheets, but Sheets lack integration with the various backends that grew over the years.
This is the standard way of getting promoted that I've seen. How do these people not feel disgusting?
Confluence is brillient, bitbucket is meh but OK and JIRA is an utter tire fire both in how it's built and what it does but PHB's and PHB-shaped objects love it.
Wiki was painfully slow to edit (and render, ~2 sec page render was typical, and I'm not counting some graphs that were asynchronously rendered).
Quip is good for fast editing, but anything that needed code formatting there is bad. It's even more "print oriented" than Google docs. Fixed page width, very fixed formatting, tables are awful.
When did you work at Google? There are markdown supported wiki tools now for internal documentation. It supports pre-formatted code, graphs, etc.
