I used the lifetime score for all three dealers. The main score shown is heavily weighted to emphasize the most recent 6 months of reviews. Value Electronics does come out better with the main score.But you have the wrong data listed for Value Electronics, they have a solid 5 star rating and the average is 9.87 of of a possible 10 being best.
Really, you probably won't go wrong with any of the three.
I get what you're saying. There was more discussion than I would have liked on the dealer ratings, but I think it does relate. All three offer deals on the CX. When considering a deal, I think it's good to know if the sellers have a good reputation.
