One of the best days I've ever had at my current job is they day we ditched Accurev and moved to Subversion. Accurev uses overly complicated concepts. Like one of the commenters above, after working with it for years, I still didn't understand the different states that artifacts could be in. It seems that Accurev's greatest asset is its whitepapers and stream visualization, both of which are v appealing to management but does nothing for developers. I use Subversion, Mercurial and Git for various projects and would recommend these tools over any other.
