I cannot speak to the others, but you are spot on on how the GM works. And this is a major problem with their testing criteria.
I have never had to use the brakes on my truck on a down hill when the cruise is set, but when approaching I do reduce the cruise setting a few clicks. Mainly because it is more unsetteling for me to be 5 over the speed limit going down, than it is going up... And that is the variable it allows before shifting gears.
In most cases, especially on a unkown to me hill, I prefer to be 5 under, so that means 10 down clicks on the CC. If a slower posted section of highway comes up, I reduce the setting on the cruise accordingly, before getting into that section. It will downshift as needed to get the speed where I want it to be. After the slow section or the down hill ends, I simply raise the CC the same number of clicks I previously lowered it.
As you can see some driver input is needed, but to me, it is better on the brakes to do it this way. And I don't think CC should be used as an excuse to stop driving the truck.
IMO, the GM EB works best when used in conjunction with the CC, even though it is not a hands off experience.
