I agree the 4L 80e is cheaper to build and can handle more power.
However the weight penalty of this transmission will ruin my handling as it's significantly heavier than the 4L60e.
How does the 4L80 E drive on road in every day traffic in terms of responsiveness and gear changes compared to the 4L60e?
If both units have been fully rebuilt with quality parts.
Does the 4L80E make the vehicle feel like a truck?

The 4l80e is NOT ridiculously heavier than a 60e.
The 4L80E weighs 178 lbs in typical configuration. A 4L60E weighs approx. 140 lbs, a TH400 weighs 135 lbs, a TH350 weighs 125 lbs. All weights are without converter and dry with stock components.
Back to back dyno between a 60 and an 80 will show less than 3% difference in HP (assuming both converters are spec'd properly)
The gear ratios are better in the 80e...not such a dramatic drop from 1st to 2nd that has always plagued the 60e
The gear changes are non-synchronous. Meaning one clutch just comes on after the other...no special timing for the release of one clutch during the application of another (like the 2-3 shift in a 60e) so the gear changes in traffic and on a day-to day basis (as well as when racing) are better.

This just goes to show how clueless you are.

You have cleared up a lot of information for me,
Don't forget this is a forum where you can learn knowledge as a lot of members have varying degrees of it in different areas.
What is not good though, is calling people names.
Clueless and ignorant because I don't know a lot about these transmissions. Only basic things.
Maybe it's true, but you don't need to be a DICK about it.
Learn to be a bit more diplomatic.
It's called etiquette.
