There have been plenty of threads arguing for the merits of this faction over that faction in regards to morality, ethics, and end goals - but which faction is, in your opinion, the most fun to play? Which faction has the best quests, most interesting NPCs, best rewards, etc?

Just getting started, so I appreciate your opinions on this.

I've only done the questlines for the railroad and the minute men, all the quests for both are "go here, kill everything." The minute men quests give you new settlements though.

Presumably you've met all major factions.

I've progressed to the point of no return with each faction and I like the BoS radiants the best. Institute did have an interesting and creepy non radiant side quest. Not sure what railroad radiants would devolve to if they eliminated their competitors
