Aside from the practical distinctions between SVN and Git, their underlying implementation also follow entirely divergent design philosophies. Whereas SVN tracks differences of a file, Git’s version control model is based on snapshots. For example, an SVN commit consists of a diff compared to the original file added to the repository. Git, on the other hand, records the entire contents of each file in every commit.

Lightweight Branching & Easy Merging ( ~ 5 merges can be done in a day).
