I like that it is easy to use for both newbies as well experienced coders with their own workflows/processes - there's not much you need help figuring out from scratch! It has helped us keep track of our projects' progress when working remotely (we're all remote).
The only thing i dislike about this tool is how slow its UI can be sometimes if we are doing several things at once or have too many tabs open within one window. We've used CodiGit primarily because most other tools were either closed source / expensive & complicated.
