I'd give you an unbiased opinion if I could. I've been a Ford fan all my life. I will say this though, the Ecoboost is a terrific motor. We purchased a trailer with similar weights as yours recently. Only towing time I've had is driving home from the dealers, 200 miles. I pretty much grinned the whole way, especially on the hills. What I would suggest, if you can, tow a trailer with each one.
If you make an unbiased choice you will probably be happy either way. But I sure like mine.
