Unfortunately I can't offer feedback on either of those, but I've actually been pretty happy with my UPPERCASE one.

I don't think it's really a big name, and the package showed an iPhone 5 and included a completely useless iPhone 5 Home Button sticker. The panel is for the N5, though.

It does have cutouts for the front-facing camera, earpiece speaker, AND proximity sensor, so that's a con. I had an Anker (unfortunately discontinued) that only had a cutout for the earpiece speaker, so I think the other cutouts are unnecessary and ruin the aesthetic.

Anyway, very nice thick glass panel, rounded edges, and it seems to have a nice oleophobic coating.

The Anker was thinner, no rounded edges, and the oleophobic coating was either very thin or non-existent. I was fine with it, but it did chip on the edge, and it seemed like it wasn't too resistant to scratching.
