Pro Fast
With Git, nearly all operations are performed locally, giving it a huge speed advantage over centralized systems that constantly have to communicate with a remote server. In addition, Git uses delta encoding to only transmit the changed pieces of files across the network, saving time in large repo...
Pro Decentralized
Doesn't require access to a central repository, because each checkout is a full repository by itself.
Pro Free and open source
Git is open source and completely free to use.
Con Commands too close to implementation details and strange documentation
Git really suffers from the lack of abstraction made during its conception. Just as a proof, a generator of git-like man pages has been created to celebrate that weirdness: https://git-man-page-generator.lokaltog.net/#7936172c3a80dc263651aaafebcb13d3 That said, the documentation is getting better...
Con Steep learning curve
The large number of commands and functions that Git provides can be discouraging for beginners. Learning how Git works can be a difficult concept to grasp at first.
Con Slow on Windows
Though it definitely has improved in recent versions, Git on Windows is still slower than on Unix-based operating systems. That said, almost everything is slower on Windows than the equivalent on a Unix based os. And also, it is still quick enough and (with most operations) quicker than other SCM...
Pro Easy to use
Mercurial is a more intuitive option than many of its competitors. The documentation is well organized and easy for beginners to read & understand.
Pro Good documentation
Mercurial documentation covers everything from revision control system basics to mercurial specific features in a short and clear way.
Con Can't delete named branches
You pretty much have to use tags instead.
Pro Self-contained
On Windows, Mac, Linux, FreeBSD Fossil is just a single binary,
Pro Web UI built in
Convenient for self-hosted projects.
Con Obscure
Not as well known or widely used as other systems like Git.
Pro Fully integrated work item tracking
For users needing more than source control, Vault Professional offers fully integrated work item tracking in a powerful, yet easy to use interface.

Con Centralized
Branching becomes a pain due to its non-distributed model
Pro Simplicity
It is quick to learn, you don't need to memorize lot of commands to do your job.
Pro Full support for renaming
Renaming of a file is fully supported, not a hack like removing a file and adding back under another name...
Con Slow developement
Bazaar tends to have a slow update cycle with Canonical. Version 2.6 was released in August 2013 and branch 2.7 was not finished until Feb. 2016.
Know any negative aspects of this option?
Pro Mature product
Fast, easy, and relatively bug free. Caching add-on ensures rapid check-ins & check-outs anywhere in the world.
Pro Great for document version control
Easy tree interface. Can train novices in 5-10 minutes.
Know any negative aspects of this option?
Pro Clear and simple operation
It has linear history, central repository and management. Lacks too complex features, almost every developer is familiar with it, so everyone knows what to expect and how to work with it.
Con Branches are hell. Conflicts are hell.
Svn is hard to use on multi-topics workflows. Branches exist but are often not used because of the fear of the merge hell. Also, conflicts are a big deal and happen on the server; it feels like you only have one try and no way to abort/retry your conflict.
Con Underlying model is totally flawed
Need to code in a rural area? Away on a retreat away from a good network connection? On a plane? Tough luck.
Pro Dynamic views
MVFS filesystem is a good approach for configuring a custom view to your files
Con File-centric
ClearCase is file-centric without UCM module
Con Slow
ClearCase is very slow
Know any positive aspects of this option?
Con Ancient and outdated
CVS is an ancient version control system that was a very useful tool back in the days, but a lot of progress has been made since then. Recommending CVS today would be like recommending typewriters instead of computers for writing.
