One of the most respected owners' surveys is the
JD Power survey as on the What Car? website. That link is for the 2013 survey results, you can search the site for whatever year you want depending on the year of the cars your considering (I think they cover up to 3yrs old, so 2013 includes 2010 onwards....I think).
It's not a hard and fast answer, but it does give a good indication of what real world owners think of the models. See the model ranking as a start.
