- Branching in svn and git are both easy, but merging is much easier in git. I have spent lots of time merging in svn.
- Being able to commit locally without being connected compliments my workflow. I can push several commits to "master" when I'm done and not one giant commit all at once.
- Lots of history in svn takes up a lot more space than git
- Rebasing and cherry-picking in git makes hot-fixes much more easy than in svn.
- Pulling/fetching source code is much quicker in git than svn.
These are just a few that come to mind that wouldn't fit in a tweet :)
