Jira is the worst possible choice, except for all the others.
Has anyone tried to use something like notion? Depending on your size you don't necessarily need all the stuff around it. Whats the difference between a story and an epoch? Most people don't really care. They just need something to track stuff being done, like a glorified to-do list with rich text.
I think Notion works well for tasks if your organization is small, or you are happy with lightweight process. There is no way to ensure all updates to a Notion page follow a strict state machine like Jira. Notion just doesn’t have those kind of validation / restriction tools yet.
For our 100ish engineers it works well especially because planning docs flow seamlessly into project specs and then tasks… but we suffer a bit from loosely defined workflows around 2-week sprints that take more clicking than anyone wants.
