Airtable

Just the variaties of ways to show data - table, kanban, gallery, calendar, timeline, form! Its incredibly versatile and means you can craft it to many different types of people from CEO, to Marketing, to Finance.

The only downside I can see is that the per-seat amount can get high for multiple team members, I wish this could be lower or to only include core team members in that amount while having 'visitors' that have less access in the document.

Airtable is very powerful. It makes database logic accessible to non-developer profiles.
Being able to view your data in so many different ways is great.
Usecases are endless.

I was disappointed by the inability to create easy-to-use apps for the final user. You can either share the entire database with them - which can be overwhelming - or cherry-pick views you want to share with them - which is impractical, especially because those views aren't editable.

This makes Airtable great to build internal tools for tech-savvy teams, but in order to make it usable by other people you'll have to use a third-party app builder (Airtable will then be used as the database / back-office of your app).

In addition to that, I sometimes get frustrated with some formulas, especially "datetime" formulas and recursive logic. These can become overly complicated in Airtable.

Easy import of Excel data, multi select fields, customizable fields

Too many "views" make it difficult to see what part of the data you are managing right now
Hard to find the export data option (it's there but it's well hidden)
Filtering system difficult in complex situations
Slow to make change
Pricing limits you by number of rows
