New Vegas by far
We could argue the points all day long but for me it comes to down to the fact that Fallout 3 is Bethesda game and Bethesda doesn't know how to make Fallout.
Sides in F3 are morally clear cut, in FNV its all muddied with every side having a clear reason, politics etc but more or less willing to throw any morality under the bus for it's own benefit which is exactly how Fallout built the world.
Characters in F3 are more self serving and don't really interact with the world outside their specific missions. In FNV most characters affect various aspects of both you and others. Their presence is felt. And, also, they have their personalities.
In F3 world is clearly divided in small sections with little to do with each other and even less overarching theme and presences. It has fun parts but it's like a theme park with rides. Pirate ship right next to space exploration right next to car racing right next to dinosaur walk. FNV feels like a cohesive wold. There are big overarching presences that are felt in almost every little corner of a game (NCR, Legion, Powder Gnagers etc), every side has it's own consistent policy, every place has it's own means of sustainment etc...
In F3 you have main story and diversions along the way which can be fun but you are meant to stick more or less with the story having to return to checkpoints to continue progress. FNV on the other hand takes Fallout approach. Here is a reason for you to do something but here is a whole world that has many other things, have fun!
And I could go on and on (about factions, characters, weapons, combat, stories, meaningful messages and allegories etc) but I really can't bother myself. F3 is a good game, but it's not as good as FNV and it's a bad Fallout. But for people who like Bethesda style open world games, I can see how F3 is a superior product.
