Xiaomi Mi Box (S905X) :

- broken Kodi Krypton dynamic refresh rate switching, consequently you will not get ultra smooth Kodi video playback from this device.
WILL do Kodi HD Audio Passthrough.
Not recommended for 4K Kodi video playback.
Not recommended for high quality Interlaced TV viewing.
Not recommended for rare H264 VC-1 compressed video content.
NO Ethernet can be limiting for some. A UGreen USB3 > Ethernet adapter may be an additional required purchase.
Same as 99% of Android devices NO Auto Resolution switching possible.
Like all Android devices not recommended for Mutichannel PCM/FLAC Audio either.

ALL Android OS's devices come with restrictions which can affect Kodi use.

Recommend for really easy to use Android TV Apps and non demanding Kodi users only.

4K Netflix (no HDR) works well with decent 5GHz N or AC home WiFi.
Superb Wireless Voice remote - the best remote in its class infact !

Any AMLogic S905 / S905X / S905D box running LibreELEC ( or OSMC):

- everything works in (4K) Kodi Krypton:
Auto refresh switching for ultra smooth video playback.
Auto Resolution Switching for hands off optimal 1080p / 4K viewing.
(HDMI) HD audio passthrough, inc. Atmos and DTS:X
Multichannel FLAC > PCM Audio output.
(Excluding 1080p 3D) Plays anything you throw at it including old legacy video compressed content.
** just be aware of the different S905 chipset capabilities in the chart below, regarding HDR10 and VP9 support.
Recommended for interlaced DVD / TV viewing because it uses AMLogic's - reliable, high quality, Advanced Motion Adaptive hardware deinterlacing.

So it seems to be that the closest to an all-in-one device will be MiBox if it ever gets Libreelec dual boot capabilities.
If only xiaomi would ever allow it
