Like Notion a lot and we looked at a number of the modern wiki tools (cloud based).

vs Confluence it is much faster. We did end up with Confluence, but that wasn't my first choice.

vs Samepage it just felt a lot more modern. That might be harsh, but we only had a limited time to eval all the options.

vs Quip, well, it's Salesforce. The sales was spammy and you just know how hard the sale will be if you've ever used the core SF products.

Best OS with a combo of Bookstackapp and a ticket system that I forget the name of now. No integration between the two, and no support.

The reason it lost in the end was it was the only one that didn't have draw.io integrated and we do a lot of diagramming. But, as I say, really nice and I would have preferred it to Confluence.
