I have been a sucker for the Moonlight Greatsword in every one of these games, especially since it was in the pre Souls FROM games. Solid weapon with some unique quirks. I used to also really like going Spear and Shield, but there just has not been a decent one handed spear with a good moveset since Demon Souls. Some of the pikes are good, though, and are relatively easy to get. In DS3, though, the sword from the giant undead king guy is very good for PvE with little in the way of major stat commitment.
