Actually I find Nobu's 1st skill is the only one that's great. Second skill is worse than Orion's against male because Divinity target is still fairly rare, and are mainly certain servants that have it, most mob don't whereas there are still mobs that's male. Orion have her passive 3 turn attack and defensive buff with another additional turn of dodge is really handy. Both of them rely on someone to generate star for them, however Nobu have advantage in terms of eating those generated stars. I think Nobu might do more raw damage? I'm not too sure on that, but Orion won't be behind, if at all. The main thing is probably this: noble phantasm. Base on single target damage, Orion is ranked 9th, with her trait counted she's actually ranked 5th. Since Nobu is multi-target let's have a look at multi target. Oh wait, Nobu isn't even in top 10. It is only when her trait pop is when she's in top 5, otherwise her AoE is mediocre at best.

So there, though she isn't exactly the best 5* out of the pool, but I personally think she have her place in terms of NP bursting targets down. Everyone saying Gil is better is purely because of Gil able to generate NP better than Orion I think, otherwise Gil's damage also pale compared to Orion.
