Both are amazing. 3d land has amazing 3D effects, exploits the capabilities from the 3DS, and it was a great surprise to be able to use Luigi later. Besides, the way the story is told is so charming!
3D world on the other side, had great lighting effects, very nice graphics, 5 great characters, and introduced the gameplay from Captain Toad,which became later on in one of the most charming games Nintendo has ever done. Neither of them was really difficult, 3D World perhaps was a bit more tedious to complete, since it was made for multi-player.
If I have to choose, I'd go with land,but world is very very close, and both are two amazing Mario Bros games!
