agree wholeheartedly
imo F3 had the darkest easter eggs (more children's skeletons, written notes everywhere, suicides, embracing skeletons) and solid, innovative DLC
FNV had the best politics/quest branches/mission complexity
F4 had impressive building mechanics (Vault Building DLC) and settlement/population management
each excels at their own thing, all allow for RPG playthroughs but I think F4 took heat from diehard fans for feeling a little too on-the-rails with your destiny and character Identity. You couldn't be anything outside of your father's son, same as fallout 3
so for New Vegas planting its character as a mysterious courier with cool, but still vague backstory in its DLC, they win the award for best RPG mobility
