I don't know if there is a nooticable difference in accelaration.
It just depends on which you like better.
Before I bought my 2003 F150, I drove a Chevy with the 5.3. If I was blindfolded, I doubt I could have told which truck I was in. Power was the same as far as I could tell. Why did I get the Ford? Cause it's a King Ranch, love that interior, and, it has a moonroof!

What can I say, I like American V-8's!
I know a guy with a 1/2 ton Chevy with a 5.3. He pulls a 20' stock trailer with 9 cattle on it. That is probably weighing close to 14,000 lbs. The leaf springs on the rear actually arc downward with the trailer on! He could outpull our neighbor with his 460, and get 10-12 mpg doing it. The 460 got about 6-8 mpg. Our neighbor got a 99 Powerstroke Superduty. The Powerstroke can of course outpull the 5.3, but it gets about 8-10 mpg. I do not know how a 5.4 compares to a 5.3 when being used like this, but I am extremely impressed with the 5.3L.
From what I have heard, the only real drawback to the 5.4L is the tranny behind it. First gear is a little on the high side. I think that the 5.4 is a good motor and is a vast improvment over the EFI 351. I do see a fair number of people pulling 16-20 ft stock trailers with 1/2 ton Ford pickups.

not sure what it is in the f150, but i know in the f250 superduty the 5 speed has a first gear ratio of 5.72. 2nd is 2.94. ive had mine almost a year now and dont have any complaints at all about the 5.4.
we have a 5.3 in a tahoe that i drive as a company vehicle when i go out of town and i dont think it would pull a lawnmower to be honest with you. it hunts for gears just driving up a hill not pulling anything. but i have no idea what axle ratio it has or anything else about it. but it has taken me offroad in places that a dodge ram with chains on its tires had to be pulled in with a dozer.
