A:Answer I was told that the 6 has an inferior processor than the 7. I bought a “dumb” 65” TV instead of a “smart” one and I regret it as it doesn’t have enough inputs and outputs. The 7 will have more ports which may come in handy for connecting a thumb drive, HDMI cable to your laptop, Firestick, etc. The $30 you save is not a bargain if 1. The 6 has technical problems with it’s cheaper motherboard and you have to call Samsung warranty dept, (it’ll take several visits to resolve a problem), and 2. If you realize you really wish you had the 7 and now you have to replace the 6 that doesn’t meet your needs. And if you want an even better picture get the 8 Series.
