all of these tiles will be tricky. "Large Format Tiles" are considered anything with a dimension greater than 15" in one dimension, and all of these tiles qualify for that designation. In order to set tiles of this size, you need to have two things in the substrate: stiffness and flatness. For flatness, the typical requirement is not more than 1/8" variation in 10' in any direction. (Keep in mind that a typical floor is built to 1/4" in 10', so this is twice as flat); and you need a stiffness requirement of l/480 or better. Stiffness is the amount that a floor moves up and down when someone walks on it, or a load (such as furniture) is placed on it. Most residential floors will have to be laid down with plywood and the substructure reinforced to meet these requirements -- and that often means that doors will have to be reset to accommodate the extra thickness. The 24" x 24" tile is going to be easier to handle.
