official history. Good for backups, accountability and security
Security: Native subdirectory-level user access restrictions
Branches are easy and stored centrally
Gentlest learning curve for newbies, and operations like branching become quite intuitive as you progress
Ability to lock files, ensuring that others don’t work on the same binary files assets like documents and media files simultaneously
Widest adoption among developers
History of changes can’t be modified
Working offline means you can’t commit changes to the centralized repository until you have Internet connection, although this does not prevent developers from working on their local copies
Generally slower than Git, since most operations need to synchronize with the central server, especially when merging large branches
Possible to revise history and preserve only successes, not failur
Git Built for development of the Linux operating system, Git is a distributed version control system that has an emphasis on being fast. Git projects lack a central repository; rather, every working directory is a full-fledged repository of its own, and is not dependent on network access or a central server. Git is convenient if you want to code offline or have many developers collaborating independently on a single branch, which is why Git is favored in many open source projects.
Decentralized model means many operations are faster and makes offline work more practical
More merge options, which are generally faster than Subversion
Branching is easier and faster
Comes with many tools like ‘bisect’ that can partly automate the process of finding where a bug was introduced
The local copy model means you need to be more careful of backing up your own workstations
The large set of commands can be esoteric and present a steeper learning curve
There is no file locking, which can cause issues with binary files
History can be changed, and being able to edit past commits might not leave the strong paper-trail you’d prefer
