It depends on what you want to read: Shounen (like Naruto or Bleach) or Seinen (lots of gore, lots of nudity/sex, very adult themes)? Magi is the former and Gantz the later.
And some advice on One Piece: see the anime for the first arcs. Along with being easier to assimilate, the scanlations available of those first arcs are really crappy (not even knowing how to write the main character's name kind of crappy).
