In my yard it mattered what I used after the new lateral system had a few years on it because my wife didn't want to start the yard over. I brought buckets of dirt into the low spots and smoothed them with the loader bucket and a rake and then seeded the new dirt and it worked real good.
Now if I was to do a yard that it wasn't a problem with existing grass etc I would till and drag it or disc then drag. A box blade takes some finesse in order to not induce bigger hills and valleys least it does for me on road work where a drag seems to do a better job on loose materials anyway.
