Nuka Cola is not "just boring soda." It's flat, 200 year old irradiated soda still worshipped and drank by many. When you drink it, you get a bottle cap (ie: money!) for free!

And if that wasn't enough, back before the Great War, the Nuka-Cola company wanted to shake things up. So what do they do? They make a version with an ISOTOPE IN IT. Drinking it apparently turns your piss glow-in-the-dark blue.

Nuka Cola is one of the main reasons why bottle caps are currency in the game. Because otherwise caps wouldn't be as common and we'd be using some crap like the rings on top of soda cans (Which happened in Tactics, unfortunately.)
