They're fantastic products. Working with Jira is lightyears better (imho) than Bugzilla, Mantis, Trac, etc... It integrates with Eclipse, SVN, and Confluence. Easily customized issue types, permission rules, and workflows mean that it's simple for us to handle development tasks, creative changes, bugs, hardware change tickets, and everything else in a single system. "Oh you're creating a feature request for Client X? I'll automatically use their special workflow so you get all the right approvals and estimates." "Oh you're entering a Sev 0 production ticket? I'll page the right people!" "Oh you want new hardware? I'll prompt you for all the right fields." Honestly I could go on and on about how much time and pain Jira has saved us and our clients. Confluence is a really great Wiki. Most importantly for us it integrates nicely with Jira and Crowd, and let's us manage many independent spaces with group based permissions for access. The wins totally depend on your usage. If you're 1-2 people, Trac might be fine (although with the new super cheap pricing you should give Jira and Confluence a try). But in my experiences at a Fortune 500, contracting for several companies, and finally running my own small company, Jira/Crowd/Confluence have been absolutely no-brainers as far as being well worth the purchase price.
