what do you gain from a longer steariing stem

maybe Im missing something and please don't take this the wrong way but its just a comfort issue, some of us like our bars higher and having a longer stem eliminates the bandaid of bar risers...

thats what i was told not sure if it was 100% but it makes sense
 
if you are a bigger person it makes the quad feel much bigger

i have a +1 steering stem on mine
