Re-evaluating SCM at my current project

Started to evaluate if the SCM used at my current is really the best tool for us. Since the last analyze of the underlying storage (and subsequent attempts to fix it) only results in "Potentially dangerous inconsistencies bla bla bla" I'm convinced it isn't. I'm personally biased towards Subversion (or Perforce if the customer wants a commercial product) but I'll try not to limit myself to these two systems.
