I'm loving the stuff InVision is putting out this year and next, but I do wish the examples they'd show would reflect more realistic websites and apps. This and Studio seem to cover a lot of the same interactions, use cases and design styles. The most important thing for me in a design tool is knowing it can cover any base, any design style and any interaction. A lot of the demos so far have been side-swiping, picture fading, highly designed nonsense. That's not really a great reflection on the apps and websites being built today.
