While Little Snitch can do general blocking from a block file, its main use is per-process blocking. With PiHole, you can't see what process on your computer is making the request, just that your computer's IP is making it. Little Snitch (and LuLu) are great, because you can see what program is actually making the request, and block/allow/setup rules for it.
