Jira exists to check every checkbox so you feel serious remorse if you pick anything else, but in terms of day-to-day productivity, it doesn't do too well. "Nice to look at" and "Fast" aren't checkbox items for managers. They're eventual problems for someone to solve when they notice engineers never touch the bug tracker.
At my current org, my advice to use Linear was overruled in favor of jira, and I'm pretty sure I'm the only engineer that regularly touches jira.
(I intentionally write "jira" in all lowercase because I like to call it JIRA, but jira's built-in text editor unconfigurably autocorrects "JIRA" to "Jira". That's the feature they spent engineering time on? Fuck them.)
