There's not really one better than the other, just a different one. Call quilt groups, churches and find out what sewing charity project they do and offer some materials for their projects - join in on the one/s you want to. Our sewing group at church makes pillowcase dresses (use fabric also for this when we run out of donated cases), we make wheelchair/walker bags for a local long term care facility, blankets for fire & police departments to have on hand for children, lap quilts... There's an unending list of uses for fabric for charity and an unending list of generous sewers out there who can always use more donated materials. Enjoy your opportunity to give so much to charity.
