My question is, what is criteria or the necessary features that a device need to a get A+
I think we should set a standard so there wouldn't be no preferences.

For now, I'm making that call based on my subjective impressions obviously, but also objective tests and overall user feedback on forums. But, if you want to develop a new rating system (maybe vote-based), I'm good with that, to replace what I'm doing now.
