Notion is now becoming a lot more like coda. I love how Coda exposes tabular data in a programmable way (but programmable as in easier than spreadsheets). It also even has API access: https://coda.io/developers/apis/v1beta1
Airtable was really bad for me compared to Notion. The rich text support is the primary but not only problem. I can't speak to the others, but Airtable is a really bad alternative.
