Should i get the iphone 6s plus or iphone 7 plus?

I'm debating on which i should get. I have my reasons for getting both. The 6s can be plugged into my aux in my car. But the 7 has a better camera. The 6s plus i'd be paying $360 & the 7 plus id be paying $670. Money isn't the problem. Just can't seem to choose!

As you say… Money is not the issue. Then go for the 7+
