They serve different roles in team comps and work in different ways against different team comps. Nasus is a faster towerpusher (though a slower minionpusher) and has a stronger objective control in the midgame if he's decently stacked. A big thing to remember is also Wither - it's ability to screw up a single individual on the enemy team (especially ADCs for obvious reasons) in teamfights is not to be underestimated. Nasus can also sustain even without hitting enemy champions, so he generally handles prolonged poke better (though Darius' team can try to prevent that by running an engage heavy comp).

To put it into simpler terms - Nasus offers more utility to his team through Wither's strong slow, Spirit Fire's armor reduction and his towerpushing threat. Darius on the other hand offers higher general damage output in fights, but relies very heavily on his hook to not risk getting kited to hell and back in teamfights - if he's left without appropriate targets in a zoned out situation of a teamfight (Imagine inside Anivia's ult, Braum's ult, Cassio's W etc etc) with his hook down, he can't really do anything - Noxian Might or not. You might argue that Nasus faces similar problems, but his Wither is generally more accessible and has a slightly longer range, on top of atleast being able to provide some utility with Spirit Fire in those situations. One final thing to mention is that Nasus has a better escape tool in Wither - Darius' CC either pulls his enemy closer to him or requires him to be in melee range, while Nasus can slow a pursuer from a distance.

So if the enemy team will play neither Nasus or Darius, they'd serve different purposes as a pick for you. I'd avoid playing Nasus against any team with a Darius in it though, simply because you two are likely to be left butting heads with each other in teamfights and Darius will generally get more out of that than you will. On top of that, he's also very strong against Nasus in the laning phase.

TL;DR A team with Nasus in it vs a team with Darius in it leaves Darius' team with an advantage since Darius does well against what Nasus offers at all stages of the game - teamfighting or not. If the enemy team isn't playing Darius or Nasus they would both play similar but different roles as your pick for the team.
