Good points Terry.
Depending on the use of the vehicle is the determining factor on what
transmission to select.
Another factor to consider is the other half - meaning wife or husband,
their driving experience with either a manual transmission or automatic.
The 45R automatic is a real slush box. Anyone drove a MB vehicle can
testify to what I am saying. If I was using the vehicle for 80 percent or
more for freeway driving, choose the Automatic. If the QC is used for
recreational purposes then select manual.

No doubt about it, the 4.7 does give more power per liter. But aside
from the engine being lighter, I don't see the relevance. The 5.9
takes more liters to make the power, but the extra liters are there.
It's still a matter of comparing the two engines, and deciding which
one to buy in a QC Auto. People keep talking about 5-speeds, and no
doubt the 4.7 5-speed is a great combo, but the original question was
asked about a QC Auto. Let's please stick to that configuration, and
talk about why the 4.7 is the better choice than the 5.9 in a QC Auto.
>rockers, rods etc). External mods added will surpass the 5.9 in both HP/TQ
Debatable, but regardless, I prefaced my question with the condition
that the owner would be doing no mods to the engine.

That means the 4.7 is capable of more, true, but if the detuned engine
is what the person gets, then that's what has to be compared when
making the choice at this time.

Now we're getting somewhere. Sounds good, but how does that actually
translate to the street and track? I'd enjoy watching a 4.7 line up
with a 5.9, same tranny, gear ratio, body style, etc., and see what
happens.
>Oh! This was the last year of the 5.9.
Good point. Would the 5.9 going out of production be a problem for
someone choosing that engine on a QC Auto? Possibly, but I would
think parts would be available for a long, long time.

Works for me! :-)
