You're right, Vue's been around longer, but Aurelia's release appears to be just around the corner and they have a team behind it, so I'd call it even. I'm mostly interested a comparison of the technical approaches since I think it's too early as yet to properly assess their communities.
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).
