2016 S-plus or 2016 S-premium?

Both black, both similar price and mileage, which one would you get? The premium has leather seats, heated seats, etc. The premium one is not a certified one.
Plus and Premium have different options : go with what you wish as long as you know the history of each. Side note : no leather in any Corolla. It's some kind of polyester/vinyl called " SofTex".
