I need advice about buying a new sedan?

I'm in the process of looking for a new sedan. I'm considering new and used options, but I think I will go with a new one just because I drive a lot and I plan on owning my car until it stops working, or hits close to 200k miles.

Here are my options:
1.) 2018 Kia Optima SX
2.) 2018 Mazda 6 i Grand Touring
3.) 2018 Ford Fusion Titanium
4.) 2018 Ford Fusion Sport

What are the pros and cons of each, and ultimately which would be the best decision?

I want a reliable, powerful car.

If not new, I would consider those same options (beside the sport) in the year of 2016.

Thanks!

(My previous car was a 2012 Ford Fusion SE, which has never given me any major issues and was a pleasure to own.)
