Personally, I would prefer CVA in CCS rather than CIS.
CVA is SO important. If CCS wasn't around, I would suggest adding it to ANY Comodo product (although for me, CCS is the perfect product so far). I wouldn't be without Secunia PSI now (untill CVA re-appears). Rather than having to check for updates or a regular basis, Secunia PSI will tell me if any software is vulnerable.
