I'll do a compare and contrast in the future. For now just enjoy the game and have fun.

Now I don't want to be judgmental about a game I haven't played yet and don't plan on playing for at least a year or two, but its well worth noting that the plot elements presented in fallout 4 will either make or break it.
Fallout 3 is considered the 'plot' of the entire series, as it goes over the fight for greater good, or basically the alliance with the brotherhood of steel to defeat the enclave and super mutants and purify the water. The player felt a sense of completion, and could align with either a good or bad side. Even in the dlc The Pitt (my personal favorite) players could either side with the people or the tyrant, putting the alignment of the player in either jesus or devil.
Fallout new vegas experimented with different plot aspects, which many people feel caused the plot to fall apart and seem inferior, especially when compared to fallout 3. Players were given different alignments, all of which were evil in some way. By the time players finished the game, they felt a lack of the sense of completion. People complained online that no matter what branch they took in the plot, the ending never satisfied.
If fallout 4 taps into the fallout 3 method of delivering plot, I think it might be considered the best fallout game of the entire series. It seems that it has so much potential at the moment.
If they od on the faction stuff again, well, rip.
