Simple tasks, such as commits, can quickly be made without leaving the editor.
Pro Quick-commit encourages smaller commits/committing more regularly
Pro Fast and easy to use

Pro Comfortable keyboard shortcuts
Pro Highlights the difference within a line

Con You have to be using Sublime to use this
Since it's a Sublime Text plugin, you have to be using Sublime as a text editor to make use of this in its full potential.
Con Git Pull doesn't work in ST3 on Yosemite
Con Hard to see which repos have uncommitted changes at a glance.
Have to click the repo names one by one to see the uncommitted changes. Remember Sourcetree Mac client having an indicator showing the number of uncommited changes.
Con Still a young client, thus so not as feature rich
This git GUI client is quite young compared to industry old-timers like git-tower 2 or SourceTree. So it's not as feature rich as you'd like. Still a very capable client for a simple day-to-day work.
