Every website is going to have some biases... some inaccurate information, some kind of preferences. I tend to visit RTINGS.com simply because they present objective data and information regarding the results, but they still make mistakes or rather the fact that not every market has the same results from the same model tv. One thing that is OFTEN wrong about samsung tvs for example, is the claim that it's imposed ads in apps...
Samsung's one option regards app ads and user oriented advertising, don't fucking check that box, and you don't get any ads at all. In fact the only thing you get at all, is on the bar for selecting app or source or settings of various flavours, is a small rectangle that is associated to the apps you already use that simply gives a "preview" of your watch list suggestions... most people don't even realize what it is as it doesn't even look like an ad and it's so small. Meanwhile i see reviewers and bitchers posting pictures of their tv giving giant ads and complaining and it's their own fault.
