So far the NXOE is nice in what works and how it flows from a user interaction perspective.
With that said, it is still very rough with some basic problems. The community feeds dont have interactions enabled, you cant like or favorite the activities, but you can comment or report them and some of them dont display the users name on the feed item unless you select it.
I did get the entire system to crash once. I went into settings and customizations, choose a new background color then set it back to what it was. The dashboard flickered and then the xbox logo flashed and i was seeing the cold boot process. I need to see if this still happens today and then report it.
For TV I have 720p, 1080i, and 1080p modes enabled and sometimes when switching channels it gets a stuck frame, but thats a known reported issue. However sometimes it also switches the format on the xbox like native, zoom, or stretch! They say snap tv doesnt work from voice commands but its working for me, even if it isnt listed in the snap center.
I did learn a few new controller shortcuts.
Left Trigger + Right Trigger + Y at the home screen forces a dashboard refresh, so it can update the friends meld or leaferboard melds if they ever get stale (happens a few times on the old dashboard)
Start Button + Menu Button in an X360 game brings up the X360 Guide item.
