The best of everything
Doing your own testing and, as Chris already pointed out, peer review are the only two sources I trust. If you believe what you see on the Internet and TV then every company is the "greenest", every product is "product of the year", every AV app "got the highest detection rate in independant tests", every Premiership season is to be "the biggest and most explosive yet", each political party is "listening to what the people want", Daz makes your clothes "whiter than the old Daz" and Vista is "A great OS" :P
