The weight per unit volume of the GE90 composite fan blade is no doubt lighter than the titanium fan blade of either the PW4000 and the Trent 800. However, being at least 20% larger in area and having a metal leading edge guard, I believe the GE90 fan blade is heavier than that of your competitors.
