It allows him to be able to survive 1 on 1 combat, which the rogue cannot do so well. Being able to turn invisible denies Dex bonuses so he can get his Sudden strike damage at least once a round. A rogue must Feint, and that is a Standard Action, so he'd only be able to do it once every other round.
Really its a question of fighting styles. Rogues will do better when there are flanking buddies, but they will suffer 1 on 1. A ninja can lay a hurting 1 on 1, but his efficasy doesn't improve with companions to help him.

What would be really silly is a Ninja/Scout/Rogue
Swift Action: Turn Invisible
Move 10 feet.
Attack with +3d6 extra damage.
Of course, your BAB would super-suck, but hey.
Re: Sudden Strike: you are convincing me, I have to admit. Question: the Ghost Step (Invisible) reads "...for 1 round." Does that mean that if you had multiple attacks (either through BAB or Two-Weapon Fighting, or both) that they would all be eligible for Sudden Strike unless the opponent could see past your invisibility? If so, that is pretty darn effective. I am pretty sure that is how it works, too.
Re: Fighting styles: this is a good way of looking at it. I was making the mistake of comparing Sudden Strike to Sneak Attack one-for-one, while the context of the rest of the character's abilities and party composition will make a difference. It does imply that Ninjas might be better NPCs than PCs, though, since it is pretty easy for players to coordinate flanking.
Re: munchkin sneaky dude. Um, wow. What can I say?
To drnuncheon: You are right, also, to look at the big picture. What is interesting to me is that side-by-side, the rogue looks better at low level (getting evasion and uncanny dodge) while the ninja looks better at high level (with lots of nifty Ki powers). I wonder if this might just lead to more folks taking the front loaded rogue (like fighter, or even hexblade) and not the full progression. *shrug*
On balance, I do think that the Ninja class is a better fit for the archetype than Rogue/Monk multiclass (although it is kind of ironic that the Ascetic Rogue Feat in the same book makes that combo more viable)! So, when all is said and done, I think I will be rebuilding my Rog/Mnk PC as a Ninja. Thanks for all the input, guys!
