If you are not going to be dual-booting with another OS, then NTFS is the only way to go. There is no question about it, NTFS is the superior FS. Not only do you get file security but you also get smaller cluster sizes (less wasted disk space, but slightly slower performance), built-in compression support, support for larger hard drives, support for file indexing, less fragmentation, more robust (less likely for the file system to be corrupt), etc. As you can see, the list can go on and on. NTFS is the way to go.
