Hey OP! We did the same EXACT thing as you. Our end user experience was super slick using Angular, but this doesn't bode well for things that, well, aren't users (we migrated back to Rails). Your post looks like it got HN-hugged so I can't read the whole thing. Either way I'd be happy to share (so we can compare/contrast) our own findings and conclusions via email. As you said, educating other developers is great!
