CDSEO has many benefits over clean-urls. Essentially, clean-urls took the idea of CDSEO and implemented it poorly. Without getting specific for competitive reasons, clean urls suffers from duplicate content issues, it blocks spidering of numerous key pages, and has various other defects. CDSEO also has a nice, clean, easy to use interface, import/export functionality, optional integrated blog software, an xml sitemap generator that doesn't generate pages it blocks in robots.txt and more.
