Tobias on the Fournova blog presents a good summary of why to switch to Git in his article 8 Reasons for Switching to Git.
The overall theme of why you should switch to Git is reduced time managing your code base, increased time for coding. This comes in many forms, everything from the speed of Git to the ability to the ease of rollback of commits. Git automates many of the tasks that you need to do while managing your code, saving you time.
Due to the distributed nature of Git, it easily handles local copies of repositories allowing you to work offline, increasing your coding time. With the expansion of WiFi hotspots and LTE, offline doesn’t happen often, but when it does and you become inspired, it is nice to be able to hammer out those lines of code before the inspiration vanishes.
Switching to Git will definitely reduce your time spend managing your code base while simultaneously increase your time for coding.
