Where I program, we still use subversion and, looking at the costs of migration, we decided not to move to git. The time and effort needed for that migration just couldn't be justified.
Subversion results in far fewer problems in these areas. Given that, in our use case, git brings nothing that subversion doesn't, I would greatly prefer to use the system that leads to less issues and greater productivity.
Please note that I'm not saying that git is bad in some kind of overarching sense. It just brings trouble in our use case.
