As I've written before, I can imagine an essentially science-fictional version of AR being potentially interesting. Wear normal looking classes or contacts, look at something, and immediately get information through some subtle communications mechanism to be determined.

VR has basically been for niche high-end gamers. I can imagine a jet flighter simulation might be good for VR but I'm not even sure that's such a thing these days. One can imagine other uses like virtual exploration but it hasn't been that interesting and a big monitor works pretty well as an alternative.
