They offer better riding positions, If your a taller guy and slump over the bars a lot they help. Also they are a lot stronger than the OEM's and they look a lot better, Most offer Antivibe clamps which help arm pump and fatigue. I own a Lonestar and a Houser, I haven't installed the LSR yet but the Houser does wonders for me, I stand a lot and it really helps. Most OEM stems are weak one good rollover or a tree clip and the stem will bend.
