You're sounding like an irrational Airtable fanboy here.
At least Fieldbook and probably also Ragic are very similar to Airtable and fill the exact same niche, with some small diferences, and they're not mediocre at all.
Probably true, I am extremely picking about UI/UX and have opinionated views on software.
Airtable does have much better documentation (case-studies, intro videos, API docs, forums), better marketing, wider adoption and growing numbers of features, these were some of the reasons I chose it over other options at similar price points / features.
Normally when I adopt a software for long term use, I benchmark as many aspects as I possibly can (e.g. setup a simple db schema, see how many metric reviews on reddit|slant|g2|alternativeto.net there are, dig through all of their documentation quickly to see how easy or difficult it is to search things, check how user friendly forums are, compare features, gauge their business-level decisions / longevity, etc)
My use of "mediocre" might be overstated here, they are fine alternatives just not to my liking.
