Dear Dos_Command_Com,
First of all, Symantic and Norton are same,meaning Norton A-V comes from Symantec. So,re-phrase your question.
Secondly, you are seeking not independent,unbiased "reports",but individual and thusly "sort of biased" vote,which may not hold water! Individual "experiences" with a particular A-V does matter, but will not stand any statistical analysis.
Thirdly, You have not stated why you are seeking our opinions. Is it for you to make up your mind or just to find out which is rated first and so on?
Last but not least you have left out many highly rated A-Vs which defeats the very purpose of this exercise! You are literally sandboxing us into choosing between the options you gave us! I personally am feeling uncomfortable,to put it mildly!!
