And sometimes the best product actually does sale the most. The problem with determining quality is, everyone has different criteria for what makes a certain product better. You mentioned bose, some ppl love the sound their products provide while others may want more base or audiophiles may want a more live concert sound. Like the old saying beauty is in the eye of the beholder. IPhone outsells every other manufacturers individual phone and most ppl who actually pay attention to phones and are in the know will acknowledge it's not the best product overall, but their are many who believe it is, because it meats their need or want.
Bottom line, sales don't mean anything (true) many great products are no longer in production because consumers gravitated to the inferior product for whatever reason and vice versa. The S6 is a great phone for those of us who value the features and qualities the phone excel at, the G4 will be a great phone to people who value the features and qualities that it excel at.
