Most reputable car rating website?

I am currently in the market for buying a semi-used car (2011 to 2015 range) and am trying to find as much info as I can as far as how well cars are rated. I have looked at both Kelley Blue Book and Edmunds (two of the most popular sites I know of) and some of these ratings seem to contradict each other. I tried Consumer Reports but they make you pay for a membership. Also, on KBB for example, I trust their expert reviews more than consumer reviews where one bad review from a person who had bad luck can drive the average rating down considerably. This is kind of a dumb question but is there a site that is known for being more reputable than the others?

For reference, the car I'm looking for is a 4 door Sedan with solid MPG and decent power… I have had Hondas since I started driving and they've been great for me, but I want to broaden my horizon. I'd like to stick with the name brands.I've researched Civic, Accord, Altima, Legacy, Impreza, Camry, Corolla and Jetta mainly.
