While I don't have any experience with Vuze, I do have high hopes for Aurelia. I've worked with the beta versions, and found the API to be pretty workable/clean. I personally like the background of the main dev(s?) behind Aurelia. IIRC, they worked on knockout->durandal->angular->aurelia, and I think the apps they stopped-by in before conceiving Aurelia have just the right concepts and features to make for a really compelling large-ish framework. A little dissapointed about how hard it is to bootstrap it though, I really like to start projects from scratch (empty folder), and found it a little difficult to just pull together easily (without downloading their starter-zip or whatever).
