I just test drove both an ecoboost and the 5.0 coyote engine in an F150 supercrew, 6.5 bed length.
I loved the linear power of the 5.0 and sound from the V8 but, if you go by the F150 brochure or online, the towing capacity with 5.0 drops down to 7500 lbs. With the Ecoboost, 9500. I will most likely go with the ecoboost due to that.
Reliability of the 5.0 should be higher than a twin turbo'd V6 I suspect.
