Have always used actual names. In the first hood I kept a cheat sheet handy until I could easily remember all 29. Just seems common courtesy. You don't go around calling your real life neighbors by the house number on the street.
And those of y'all who use farm names better hope nobody ever decides to prank you when you have two farms at the same level and simply for a hoot use the same farm name as the other of the same level...
