Which would you buy: the brand-new Galaxy A8 (2018) or the year-old Galaxy S8?

So, Sammy's flagship is almost a year old by now, sure. But it's still arguably a bit more powerful, with either a 2.3 GHz Exynos 8895 or a 2.35 GHz Snapdragon 835 under its hood, still looks arguably better with its edge design, and has a camera, which we felt performs better. So, for a little bit of money, you get a noticeably better, albeit older, smartphone.
So, that said, we wonder — pretend both phones are available in your region, would you go for the brand-new, slightly cheaper Galaxy A8 (2018), or would you drop your cash on the year-old Galaxy S8?
