Moore. I've been on this kids bandwagon (as well as Creer's) since they were being recruited.
I think G. Jones is probably a better all around player/ATH, kind of like a Percy Harvin (although not nearly as electric...cross your fingers for next year perhaps though?), but I think Moore might be a better receiving threat. He is definitely the best deep threat (that we have seen utilized, anyway) on the team.
With the misuse of the players by the previous regime, it is almost impossible to tell who is better than whom. So time will tell. But I am thinking Moore will earn a spot on the outside as a burner, probably with G. Jones on the other side, although I could definitely see Jones getting some work in the slot.
