As Lokaius said, it depends entirely on your purpose. If you're aiming for the brothers, infest world 5 (since many nodes - higher chances of them appearing), for clearing daily quest choose map in which you grind frequently. I suggest 5-4/5-3/6-2 since most probably you're going to infest them anyway in search of rare swords and they fit both purposes.
