It's horses for courses, if you're likely to tow a lot and load the
truck up then yeah a bigger more torquey engine would be the go but to
add some perspective, modern Merc V6 engines produce more horsepower
than the Euro version M100 but not as much torque.
However if you do the occasional tow and load er up now and then, a
smaller more efficient engine would be alright. Guess it also comes down
to which is the better engine, no point cheaping out with the V6 if the
V8 is a more reliable engine.
How much extra do they want for a manly Diesel version, you could put
vertical stacks on it and some air horns and hang out at truck stops.
Oooh don't forget the balls out the back

IIRC, the V8 has more torque, which is what a truck needs.

Well, no. Not really. But sort of.

It's a good first approximation. Torque maps to
acceleration, whereas horsepower maps to top speed.
A 200HP 400#' engine will likely be _far_ more drivable
than a 300HP 200#' engine, assuming equivalence in other
broad parameters. (RPM range, reasonable number of
gears, etc.)
The physics principles say "no" - horsepower is horsepower. But -
the perception of the person controlling the engine speed says
"Physics - go jump in a lake!".
I suspect your definition of "drivable" is probably similar to mine
- if high RPM (with high noise and high fuel use) is necessary to
"access" the torque then it is less pleasant to drive. Thus if
your 200 HP engine required high RPM to get it's 400 lbs-ft of
torque but the 300 HP engine had it's 200 lbs-ft available from a
low RPM I think we would consider the 300 HP more drivable. (I
realize that with most modern internal combustion engines the
scenario I just mentioned is unlikely).
So with a suitable transmission, and a willingness to put the
engine in the right RPM range, the 300 HP engine will out
accelerate the 200 HP. Probably. Though torque curves,
transmission ratios, RPM limits, etc. really muddle things.
