We are internally all git (with some github external stuff, and gitlab internal repos). So everyone know (as far as anyone can!) git and its way of working. Cannot say the same about SVN. Although I have used it in the past, I cannot remember a single thing about it! So from our point of view, and working for a company who are likely to do some CB dev work in the near future, git is obviously a easier route in to it. It also means we could use it easily internally, making it easier to push out PR's
That said, I've cloned the SVN stuff using some sort of git-svn process, and do have a git tree of the SVN repo. Took forever to clone it, but it's here now, so will see how well that works.
