[FRIAM] Version Control Systems .. Experiences?

[Owen Densmore]

I've recently moved from my old hosting service, HostGo, to a new one,  
Joyent.  So after getting the usual out of the way: dumping mysql  
databases and reinstalling (converted to utf8), moving my web site,  
ditto for email and mail forwarders, I started looking at other  
features I'd like to start using.

One was version control systems.  So I beam into the "how-to"
   http://wiki.joyent.com/shared:kb:version-systems
.. and was blown away by the number of choices!
- Bazaar 0.91
- GIT 1.5.3.6
- Mercurial, version 0.9.5
- Monotone, version 0.37
- Subversion, 1.4.4 (with Ruby, Perl and Python bindings)
- svk, version 2.0.1
.. and a bit surprised that CVS was NOT there!?

Wow!  Who'd have thought there'd be so many.  Wikipedia to the rescue:
http://en.wikipedia.org/wiki/Category:Free_revision_control_software

But I'd like to poll folks here: Have you had any experience with any  
of these?  What are the pluses/minuses?  If you had to start over,  
which would you choose?

Thanks,
