No, I haven't. I've primary managed projects over the years using various amounts of trac, basecamp, ms project and even mediawiki. It's important to note, however, that it's not always about features, and my first impression of MantisBT looking at it now was mostly defined by usability, so much so that it's hard to tell what features it actually has. The interface on the demo is very noisy. Redmine behaves like a modern web app, MantisBT appears to behave like a no-frills, late-90s bug tracker. That's probably fine for a certain set of developers, but I use Redmine because it's a replacement for both Basecamp and Trac (and fits the workflow of me and my company better than each), and I'm able to use it to manage non-technical projects with non-technical members alongside technical projects with technical members. Usability is hugely important. It's not just an asthetic issue. Take, for instance, the issue listing: http://www.mantisbt.org/demo/view_all_bug_page.php http://www.mantisbt.org/demo/view_all_bug_page.php or even worse http://mantis.simplepressforum.com/view_all_bug_page.php http://mantis.simplepressforum.com/view_all_bug_page.php Especially in the second example, I have no idea what I'm looking at. There is so much information that needs to be digested before I understand what's going on, and it's hard to digest it because there is a lot of visual noise and overpowering colors. And then once I figure out what's going on and decide I want to look at a ticket, I have no idea what I'm supposed to click to open a ticket (apparently the ID) In contrast, here is Redmine's version of the issue listing (this isn't my project, just an example with the same theme): http://redmine.lighttpd.net/projects/lighttpd/issues http://redmine.lighttpd.net/projects/lighttpd/issues Anyway, I hope this is useful.
