I've watched a lot of Kirby videos and noticed that many people use the forward and back grabs.
The back grab is basically the worst of the four, the forward does small damage as well, only good for comboing, which I rarely ever see.
I see mostly the down-grab, which while does slightly more damage, does not propel the opponent very far, and isn't too useful for comboing.
Few people use the up-grab, which does moderate damage, but sends the opponent flying, as well as changing the fighting location to a higher spot, where Kirby is in the open and has more potential with his aerial-superiority.
Anyways, just wanna hear your thoughts.
edit** also could be since everyone is scared to death of kirbicides, but that's been removed in Brawl, unless you're on a moving platform.
