Still not accurate IMHO... I bet if users didn't vote the way they did, SC would never pick these 4 as finalists. Just like we see those different antivirus reviews all over the internet... some are bad, some are good. Maybe SX would pick these 4, who knows... but for sure, this shouldn't be any guideline for how good some software is... maybe just how popular it is.
Some other things can tell us much better if program is good or bad... for example, technical support, how regular updates are, software team and clients/customers relationship, and some other factors.
