i am not quite sure what other benefits it has but its not a struggle at all if you follow the directions. instead of using a wire i used a small paper clip and i got it in the first shot
BE CAREFUL WITH THAT PAPERCLIP!!!! the parts of your phone being touched with that paperclip are very sensitive, the reason they're being touched is to short out your phone for the exploit, so if you have any kind of static energy on you, it can literally fry your phone, thats why they tell you to use an insulated wire.
but other benefits to s-off include:
more options and higher probability of getting out of a brick
flash splash screens
flash radios and kernels in recovery (like the one for arhd)
superCID (to flash other carriers RUU's)
and a few other little things like having your hboot say juopunutbear
(literally translates to drunken bear, thats why they give him beer, fyi)
hope i helped
