I usually seem to be a little different than some others, but physically, I have a hard time going prone (age and damage), and I can only sit on the ground so long before everything goes numb...that restricts me to a low chair/stool and I have a hard time finding shooting sticks that are really stable other than the ones I made from "Varmint Al's" website...out of some 1x2s...
Most of the areas around here is either brushy or you are setting up along a tree line and I really prefer to use a carry sling for speed and maneuverablity. I guess it's just the way that I was taught when I was a kid...but the tension of the sling gives me a much more solid platform...I usually don't have the luxury for taking "long, timed," shots...like you see in some of the videos...
