Notion is alright for collaboration, but I don't really like it for anything else.

The search is so slow that I'd rather just have all of our technical documentation as a Markdown files in a Git repo than in Notion.

I moved to Notion from StackEdit (because it's basicaly abandoned and I had bugs editing on mobile) and I really miss storing all data in git repository (private GitHub repo).
