Pretty much the best gun in fallout 4, light weight, packs a punch with sneak headshots, suppressor can be obtained almost right out of the vault…
Which makes it ideal for taking out Ann codman from home plate rooftop without aggroing the entire city early game.
The gun is viable even later game if one can find a good legendary prefix ( sneak headshot from two shot/instigating .50 pipe bolt action one shot everything except sponges like mutant warlords, sentries etc even on survival )
