are you towing much OP?
Im going to board the ecoboost love train. i've been very happy with mine. i've seen fuel consumption as low as 9.8 on the highway, and usually 15s in city. it also hauls ass and cargo very well (and i have 3.31 gears). i also like how quiet it is. i don't need the v8 noises to rustle my jimmies. its just nice to drive around and not have to wind it up to get anywhere.
if you're doing minimal hauling/towing, or lighter stuff, maybe check out the 2.7 ecoboost? i drove one this summer and fell in love. it simply goes. it felt like it had a bit more pickup than the 3.5, but obviously a bit slower. also managed to get in the 11s in city and low 9s on the highway.
at the end of the day, go test drive a bunch and see what you like. we can only provide personal experiences and advice.
