Often times they are essentially the same layout, the only difference being the “tiled” prints are already cut into pieces suitable for most home printer sizes. A4 or US letter.
As Hai-Lee stated, you can open the full prints in a program like Adobe Acrobat and use the poster print function to spit the print to fit any size paper you would like to use.
On the other hand, I specifically set my full size prints with a different layout than I do with tiled. When I lay the tiled prints out I do it in such away that minimizes cutting and taping seams even if it means wasted paper.
I would use the pre-tiled plans if you plan to print to A4 or US Letter sized paper. If you have a very odd size paper, or have access to a wide format printer use the full size plans and acrobat to cut them for you if need be.
Just remember most printers default to "fit to page" printing. You always want to make sure you set the printer to 100% scale when printing plans.
