I've driven a 2020 non etorque, and my current 2021 rebel which is etorque. I just don't think the numbers are there, because I really don't feel it.
The thing I'm confused about between the 2 engines is mpg. Yes, etorque is an assist, but when it shuts down at a light for 2 mins. That has to play into something. The "official" numbers between the two is what..1 mpg? Sitting at a light can drink more gas.
Just odd with this etorque system, and I'm learning alot in the last 1k miles. Braking is different.

I think (my opinion) the "official" numbers use a low average for stop lights. Very few lights around me if any are 90 seconds which is what the RAM numbers are based on. Lights here average 3 minutes. Second is the density of the traffic lights, this will also impact the economy.
I had about 300 miles on this tank of gas @17.8 mpg. When I disabled auto start/stop and drove around in the city I lost almost 1/2 a mpg.
The thing that I'm just now realizing is that I had averaged 17.8 for 300 miles the dropped 1/2 mpg in a short time. To impact a 300 mile average that drastically in such a short time by not engaging auto stop/start has to have used a considerable amount of fuel.
The kicker is that in a day of driving with auto stop/start re-engaged, I've only been able to recoup 2ths or about 1/2 the loss which further suggests to me that I took a huge hit in mpg.
Doing the math, I drove about 60 miles of city driving with auto stop/start disabled and now have an estimated remaining range of 60 miles which means I used about 4 gallons of fuel.
That 60 mile average comes out to 15 miles per gallon or about a 2.8 mpg difference. I consistently average 17.8 - 18.5 in mixed city driving, mainly city.
People can claim that etorque and auto stop/start doesn't offer any savings all they want but unless I've done some math wrong somewhere, it seems to be worth almost 3mpg for me. Obviously if you have a significant amount of city driving, etorque would save you fuel and if not, etorque wouldn't be a benefit for you.
