Real life comparison of 3.5EB vs V8

I towed my 5000 lbs trailer (old square box, not aero one bit) and loaded truck up the mountains this summer, 3700 feet up . I had the coyote screaming quite a bit going up the hills and I never hesitated to give it to her. I know the Eco would have given me a less eventful pull up those hills, but I can tell you that I had a nice feel of a strong, steady pull all the way....the 6 speed is indeed different than the 10 speed. 12 Mpg avg for that trip thru the Crowsnest Pass while towing. I climbed a few hills at 70mph in 3rd gear. Don't regret my V-8 one bit. Once the Eco V2.0 has a few years behind it, I'll see...but I plan on keeping my truck about 10 years....again, we'll see.
Ive towed the Pass with my 11 EB, a 15 Silverado with the 6.2L and now the 17EB.
While the 6.2L Chev is more powerful the the Coyote it makes its power the same.
Like you say you just gotta give it to her.
The EB is simply more relaxing to pull with.
They both do the job.
Ive got a loaner Coyote F150 for a few days while my dash is getting replaced and its fun to play with 5L but miss the low end of the EB.

Guys they both pull well, turbos help at altitude no doubt, the 5.0 uses RPMs more than an eco. We all know this stuff, we also know the 5.0 handles extreme heat better under load and is better for engine braking. There are trade offs in every choice.
Now in regard to 5.4 vs 5.0, the torque differences per rpm are very small, and the HP difference at rpm a little larger. Everyone focuses on torque, but torque gets you moving, and HP keeps you moving up a hill. The 5.4 was torque biased to the heavy side, and seemed to fall on its nose when the RPMs went up, due to lack of breathing ability. The 5.0 is a better combo of both virtues a V8 can have, respectable bottom end, with the ability to wind out the RPMs for extended heavy load work. You all know I worked my 13 5.0 hard, at or slightly over GCWR but at max or just under GVWR all the time. It's a great engine, really in my opinion the true jack of all trades engine in the 150 lineup.

The 5.4L 3V is a well breathing engine, falling on its face at high RPM is a characteristic of long stroke engines. The 5.4Ls torque comes on sooner and peaks at 3,500 RPM.....it’s all in the mid RPM range, 365 lb ft on gas and 390 lb ft on E-85. one of the best torque curves of any modern V8 IMO. But like you said, this comes at a price to horsepower. I agree, the 5.0 is a better jack of all trades engine and fits more duties. If let it wind out it has great peak power higher in the range, and it’s torque curve isn’t bad by any stretch. The 5.4L is nice in that it has a cast iron block and strong bottom end. It was designed specifically as a truck engine so it’s designed differently (E-series, Super Duty, F-150) The 5.0 was designed for multi platform use and is better for day to day driving and occasional towing and has a lot more ponies to keep things rolling. Here are the torque curves from last gen:

Personally, I don’t care if you’re pulling with a 4cyl Ranger or a F350 diesel. Don’t be in a hurry when your pulling a trailer and I certainly don’t recommend using cruise control when pulling over mountains at high altitudes.
I care more about my cargo in and behind my truck and the fellow drivers around me then I do about engine choice. Leave a few minutes earlier, your campsite isn’t going anywhere.
Oh wait.... this is an engine debate again. Disregard the above.

Of course, I would have liked to find a truck exactly like mine in sig with a 3.73 rear, but its rare as pope' poop. Ford knows that equiping all 5.0L with 3.73 would steal 3.5EB sales, lowering the CAFE emission targets.

Couple questions: 1. what gen was the other F150? What gears? What transmission? Engine? Cab/drivetrain? There are multiple V8's across different generations and different transmissions too. For all we know the other F150 was a 2009 with the 5.4 and 4-speed. Maybe it's a 2017 with 3.73's but that 10-speed still provides an advantage in gearing over the 6-speed. Pre-2015, the truck is probably carrying an extra 5-600lb, add that to 500-1000lb more trailer and that's significant.
So good job coming in, thumping your chest, ****ting all over the V8 while providing zero real world information to compare. We know the EB is better towing, we also know that it is better at altitude. Who cares. Mine does the job I need it to do, yours does the job you need it to do. Good for me, good for you.

Really liked my 15 EB up until it started leaking coolant at the turbos. I ditched it for a 18 5.0. 5.0 is definitely wimpier down low but isn’t a slouch at all. I’ve had both and both are great trucks and very powerful engines. I just didn’t want to deal with the ongoing design flaw of the EB.

It's hard to conceive that a V6-3.5L engine has more torque than a V8-5.0L at RPMs before the turbos kick-off where displacement alone is in action... It seems BS to me. When the turbos flex their muscles I can easily accept the upwards graph line of a skyrocket, but until then... Sorry, not buying!
In real world use though I can see a couple seconds of delay for the EB to shoot past trucks with other engines. What some call turbo lag I understand as RPM rising?
ps: nothing to say against what you wrote, it's just the graph that hit my eyes
