Absent a dyno or 1/4 mile times, all we have to judge by is how it feels to drive it.
I don't really have an opinion on either side of this, but I do know that what a driver "feels" in the seat of his pants isn't always the whole story.
Example: If you were to drive a 2000 SS Camaro (I owned one) and the late model supercharged Mustang (I'm blanking on the year), you might think, as I did, that the Camaro felt faster than the Mustang when the reality was that the Mustang was significantly quicker (about 0.4 sec on the quarter mile). The reason is that the torque curve on the Mustang was flat (i.e. constant) which translates to a constant rate of acceleration, while the Camaro developed torque as the RPM increased making the rate of acceleration increase as well.
To the driver the Camaro felt like a run away train that just kept getting faster while the Mustang put you back in the seat immediately but then felt about the same from there.
If your truck felt faster it could be that you lost some of your low end torque making the torque curve more like the Camaro than the Mustang in the example above.
