Stuart, I totally get why folks make that decision to go the non-MS route. For me, Im inclined to just use Google Docs or things like SimpleNote for my personal use. But at work over time I’ve just been more inclined to use the stuff that my university provides as it makes it so much easier to collaborate and integrate tools. In the U.S. that typically means either Office 365 or GSuite. One thing I will give MS credit for is that they are much friendlier to non-Windows folks these days. I use a Macbook Pro and iPad Pro as my work devices and all the MS apps run really well on MacOS and iOS. They even have developer focused apps like VS Code and Teams available on Ubuntu. So I think for most folks it would come down to “what has your organization adopted” to see if there are more useful things available for your in the suite.
