Our pricing is here, you can check it out for yourself:

In short: We cost a little bit more, but include features that are separate, add-on products for Jira, and generally software developers are a _lot_ happier using FogBugz. If you want to know more, just drop us a line; don't want to be too spammy here.
We're probably too small to be worth your time, but JIRA is offering $10/yr for up to 10 users, $10 more if you want the JIRA Agile features too.
