I agree with pretty much everything here. Only a minor difference in that I've found that shadow monks almost as good as rogues for sneaking, but that's sort of pedantic and doesn't take away from your point.
I've found shadow monks even better than rogues and bards at sneaking, especially underground and in other dimly-lit settings. Invisibility + Pass Without Trace + Shadow Jump >>> Expertise + Reliable Talent/Enhance Ability/Dex. Even better if they cooperate though, so the bard enhances the monk's Dex. On average that will beat a perception score of 41 at twentieth level, or 39ish at 11th level. Shadow monks can ambush ANYBODY in my experience.
