SVN was a good enough version control system (VCS) and sometimes even a synonym for VCS in everyday talks. However, technologies change and the way of developing computer software as well, in my opinion, SVN became some kind of “disturbing” or “breaking” thing in development process. It’s slow, centralized and linear. I mean it’s really slow. And when Git was introduced, usually nobody realized how it’s different to SVN and why we need it. Today it’s de-facto standard for VCS. It has a bit different logic, but you can get used to it relatively quickly without any problems.
