"Where is it compared? When have you used a gas engine, with same displacement, on same hill with same load?"
It's kind of a mute point. The exhaust brake has become a standard feature on HD diesels. A feature that works well and is a real difference maker.
A feature that HD gassers simply don't have. There is no comparison to be made.
We don't need to get into load, displacement or any other factor.
The gasser does not have an exhaust brake. Ultimately no exhaust break is a deal breaker and a major shortcoming of a gas engine

There is no doubt exhaust brakes work. If you do turn it off, then back on while going down a hill. And nobody that has ever compared can say diesel, with no exhaust brake, or it not functioning, will claim gas engine does not slow more.
What nobody wants to compare is normally functioning gas engine to like sized and loaded diesel with exhaust brake.
The Cummins for some unknown reason pretty much freewheel without the exhaust brake on, where as the V8 Duramax and Powerstroke provide a degree of grade braking.

Except thatโs what is actually being compared.
I can roll down a 6% with a 6ton trailer behind the ole 4th Gen and basically never touch the brakes unless I want to call up a downshift, but Iโm usually in manual anyways, and a new 10 speed gasser pulling my boat of about half the weight is on the hooks multiple times.
Itโs not even an apples to apples comparison as the exhaust brake will win 10 times out of 9.

I had a couple of mid '70s Macks, 1 had factory installed jake, the other had add on exhaust brake. Driving and maintaining them, I can say for sure they don't really have similar effect. Jake far and away better.
In the HD market, for likely 25 years a compression brake has become pretty standard. And while the laws about compression brakes are on the books most engines make about the same noise pulling hard as slowing. Inside cab noise standards might of caused a redesign. And most operators understanding the engine is designed to work best with mufflers also reduces that problem.
On this site, any time somebody asks about using spark plug engine to move their RV, 1 of the next 3 replies will be YOU WILL BE IN THE TRUCK LANE ALL THE TIME! In a day's drive, the time spent going up or down a steep enough to really slow you will not reduce average speed by much. Either most can't do the math, or the fact somebody passes them is a insult to manhood.
With all the issues with diesel emission systems, and cost to repair, not sure I would want to go that way.
