Between FlyFF and Maplestory, which is BIGGER to download?

I want to download either the games FlyFF or Maplestory, but I want the smaller download. So I don't want to download the bigger one, which game is bigger to download? I do NOT want to download the bigger download. Thanks.|||FlyFF is not so great at all. Go for Maplestory. Or download Fiesta :]
