I've used it at previous places of work. It's nice. Snappier and better looking than Jira at least. One of the previous advantages of using it is that everything has a keyboard shortcut, so if you learned that you could be very efficient with it. Nowadays, however, when an LLM is shuffling my tickets around, that feature is kind of useless and I'd probably prefer Jira simply because they integrate with everything under the sun
