I think the Toyota stalk is, ergonomically, the easiest cruise control interface to learn. It's intuitively very simple. Up for faster/resume; down for slower/set. Pull to temporary cancel. Push the end button to turn the whole system on or off. It's also right on the steering wheel, right where your fingers/hands already are. You shouldn't be required, in my opinion, to take a hand off the wheel to use the cruise control.
I like Honda's system on our CR-V well. The cruise main button is right on the wheel next to the other buttons. Then it's tap the rocker up for faster and down for slower. It has a separate cancel button, which is also great. The buttons are also lit, which is nice for night driving (but they're easy enough to remember anyway). Our Acura's system is similar, except that the cruise main button is on the dash. I never could figure that out.
The big shortcoming with GM's stalk-based system is there was (on most, anyway) no way to cancel cruise without either turning the whole thing off or tapping the brake. Tapping the brake should not be the mechanism for canceling cruise control, and indeed can have undesired consequences with more traffic on the road (especially at night, where others' seeing distances are naturally shorter already). I owned a number of GMs with the stalks and it was a rather non-intuitive design. Compound that with the fact that the markings would wear off the stalk...and it could be harder to use.
I rented an '05 300 once with the Mercedes stalk, and that worked pretty well. I'd rather something on the wheel where my fingers already are, but if I had to have it on a stalk, I prefer that system to GM's.
