When I first started using clearcase I hated it. Now many years later, I really appreciate the power it brings to the table. Sure it has negatives just like all vc tools too, but the easy branching, dynamic vs snapshot views, automatic merging, the ability to merge directly from a fellow developers views, etc. has really made my team more productive. However I will say that it takes considerably more expertise to setup and maintain that something like svn or git. So there is the added expense of having full time clearcase admins.
