I've had the phone for a day now, and it seems rather excellent. The RF subsystem is outperforming that of my 1+1 -- works fine in the heretofore dead spots.

That was priority one for me, and the only reason I wanted to replace the 1+1. Now I just have to decide which distro.. err.. "ROM".. to run on it. Stock is okay, but has very limited customization options, even with Xposed on top of that.
