Being able to create corpses out of thin air is pretty awesome. Even one or two early on can help Nico's defenses (by creating mindless zombies) or by making it easier for him to summon bigger undead sooner (rogue necromancy much?). Against anti-resurrectionist crews (ie Justice, or any other crews that use/steal corpse counters) you can companion with Nico, create the corpse, and Nico can use it right away without fear of it being stolen.
In summary, I think he's worth the points, and a solid buy when facing those crews. If you're not facing those crews, I'm sure there's other models you can take instead that are also worth their points, and naturally you'll use different tactics based on which models you choose and which stategy/schemes you end up with.
