It has a snappy interface but in some respects it's very heavy - ie in the number of clicks needed to do anything.
The main one for us is estimating. We want to be able to go through a list of stories and edit the estimates. The fact that the table of stories isn't editable means we have to open up the dialog for each story to edit the estimate.
As a comparison, we're currently using Airtable for some projects and Notion for others. In both of those, you can do that.
Also the ability to add our own fields to stories is something we use quite a bit.
Otherwise it's pretty nice.
