In terms of pricing it is $100 cheaper on starting base users. I found it very easy to install and to get up and running with a 25mb install file. It has parallel development capabilities with branching, private workspaces for each developer as well as remote and distributed development. It also supports ACLs for each element in the system so the security is very powerful. Finally I run it off Windows and with Visual Studio 2005. However it can off Mac, Linux and Solaris. It also integrates with Eclipse, VB, Visual Studio, JDeveloper, TTS, Jira and Ontime from Axosoft. I have found it to be good for my use. However I would recommend testing it to see it fits your requirements.

I would look at Plastic SCM. Been using it for awhile as it has many features for a very good price.
