I think Notion tries to do too much (a database? really?) and because of that it's not _great_ at any. Yes, at the end of it you can end up with pretty looking pages but the process is not fun. For example, you _can_ use Notion as Trello, but it always feels like fitting a square peg in a round hole. (a path which Slite and Quip also took)

Apps like Bear on the other hand, don't try be a smarter paper and end up being great at their limited use case.

Maybe, for enterprise customers it has some value, but as a personal user I didn't find much utility in it.
