Having used subversion and git in big teams, I can tell you the single fact branches are free in git changes the way teams interact and is worth every learning curve or design flaw in git. From spending half a day per branch copy, to releasing only a few times per year because branches are expensive, to never changing more than the minimum because can't branch-test a feature fast, to days of offline CI because bad merge on only dev branch, to keeping 3 copies of the entire repo to do backports because not easy to shift branch... SVN never again.
