I think Jira is among the better in the enterprise software class. Compared with ServiceNow (different use case but also enterprice-y) I much much prefer Jira. For example, the URL structure is sane.
Sure, it can suck so incredibly bad. But it can be really good too, depending on who built it up.
But I agree that the URLs are terrible, it's slow, and it's too easy to lose things along the way. Especially custom things
I say this as someone whose job is to help manage my company's sn instance and clean up the utter shite left behind by our predecessors
And we all get crushed under that weight.
I so much prefer Jira.
Who works on this software? Who wants to go to an interview with "workflow and usability lead on service now, 5 years" on their CV!
