My 2019 has the E-torque. I was dumb enough to believe the marketing BS and ordered it that way. My son has a 2019 without it. I've driven his and there is no difference in off idle or low rpm performance between the two.
The braking assist feature does work. It works so well, that when descending a long, steep mountain, you lose all gas mileage efficiencies by just letting the truck coast down. It slows you down well below whatever you may have your cruise control set to. It actually causes MPG to go down, not up. And yes, I've ran the numbers and the same stretch of road enough times to know I'm not full of crap.
The auto-start feature works most of the time, but I've also been in traffic, first at the light, to only have the damn thing not start when I release the brake. It's happened several times, with pissed-off folks behind me, laying onto their horn, as I fumble around and get the truck moving forward again.
If you like the feature, good for you. Me - I hate it. I hate on my truck, and I hate it on every damn rental I get that has it..........
