The Navi River works perfect. You never feel like you’re looking at a screen.
Rise vs. Ratatouille... I’ll have to tell you my thoughts later! (Sad that I haven’t been to Paris to see it yet but oh well.)
I've never been on either! Just going off ride videos, so of course the in person experience could be different. Rat looks like it's almost entirely screens, though, with basically one exception.
And yes, Navi River does so many things right -- it's just about half as long as it should be and needs more AAs.
