The knobs are fine and shouldn't pose any vibration problems like the levers. I don't know of any binding problems with the lever just the internals. These will still be there with the electric actuator your just won't know it.
How does the knob keep you from trying to go into low range? Is there a detent?
SMorneau, your comments may, or may not, have been valid for the earlier generations but they're not true for the 3rd gens.

The AA LSDs give nice, smooth, even traction to both wheels (even if a "touch" of brake is sometimes useful). "Put your rearend sideways"? Not hardly!
If, by "lose steering" you mean increased steering effort, you'll find that to be virtually non-existant at speed and only marginally noticeable at, or below, walking rate. On the other hand, if you meant loss of steering control, you might want to rethink this: at worst, 4WD provides you with a Front Wheel Drive vehicle whose rear tires give a bit of "push".
The issue over the "dial-a-drive" concerns the documented requirement to have the transmission in Neutral and be travelling less than 5 MPH before the transfer case will shift into (or out of) 4Low.
When I was preparing to order my truck, I was unable to determine which would be the better choice: LSD or 4WD. Fortunately

On-road/off-road, mud/sand/wet grass/snow/ice/dry pavement, empty/hauling, I couldn't be happier with the way this truck handles.
