If I had the choice, I'd use Poi over Trac and that's because Trac does not support multiple sites very easily. Almost every company I've run or worked at over the last few years has been primarily a consulting company. I spend my day dealing with multiple projects, sometimes an insanely high number.
Simply put, Trac does not do this. From the Trac wiki:
Right now there is no support for sharing information between projects.But in a world where all I have is multiple projects, this is a problem. Poi allows me to:
The rationale for this is that the scope of Trac (1.0) is to manage a single project, and do it well. Support for larger multi-project management adds a lot of complexity, but is planned for post-1.0 development, probably as a separate framework around Trac.
- Have multiple bug trackers, the permissions on each individual tracker is configurable, so different clients can have different trackers and can't view each others.
- As a developer, or project manager, I can have one page that lists all bugs assigned to me, across all the collectors. Such a summary page is invaluable to me.
Not that Trac is bad, there are some nice features in there. The viewed source for SVN, checkin messages that are interlinked, closing bugs from checkin messages and so on are all cool.
The only real downside is that Poi does need a bit of work and cleaning on an install, something that raises the bar a little. But that's only if you are being a perfectionist about it.
