Notion is a fantastic app, but it doesn't have a self-hosted version, which is a big turn-off for us. We have read somewhere that a self-hosted version was at one point on the roadmap, but it's nowhere to be seen now.
The main dealbreaker of AppFlowy is its lack of easily-deployed web frontend. One may exist, but it will require some manual effort. Others have moved to have the web app bundled with the main cloud image, but who knows when that will happen.

Cons:
For sure a top contender.
Pros:
Cons:
Not quite adequate for what we want. It lacks the object types that we want, and OIDC was such a pain to set up (though now we have a Keycloak instance, and we're not taking it down…).
