If you roll, you sit on the stinger instead of your hood (hopefully). If you run into something, or slide up something with a steep entry angle, you scratch or dent the stinger and not your bumper/hook/winch/lights etc..
edit: I don't like the look of the big ones, but I do understand why people have them for buggys and rock crawling etc.. I do however like the look of a smaller one that's not too obtrusive.
