Hands down the best in the series. I am replaying it for like the tenth time in 2021 and it still holds up. Even without mods the graphics aged well. On top of that, the story in New Vegas, as well as all the things to do outside of that, are near flawless. It blows my mind to play this game now, knowing Obsidian only had 18 months to develop it using Bethesda assets. I miss the karma system that is lacking in the Bethesda Fallout games following this, among other features present in this game.
