My opinion: All that is needed is 8 GB of Ram you will never use more than 6 GB Ram out of 8 GB Ram. But if you want top of the line then 12 GB will be Amazing!
All estimated cost are close to price, depends on Carrier & Country because some carriers may have the 1 terabyte storage of $1750 cost $1730 or could be as little more, way less if you trade in a phone to cut price down.
