@robertoafarias I have both and the output looks identical to me. Both send an untouched 4K stream with HDR metadata to the TV.

But after testing both devices, I have decided to keep the Minix U9 for the following reasons:
- I use TVHeadend (with a SAT>IP server) on my NAS and I have found switching times in MrMC to be slower than in Kodi 17 (LibreELEC 8.2.2.3) or Kodi 18 Alpha (LibreELEC 8.90.2)
  This may be due to older version of Kodi that MrMC is based on, so a lot of PVR optimizations are missing.
- The deinterlacing (Yadif 2x) on the Apple TV 4K looks nice, but on 1080i channels, I have a lot of dropped frames.
- The integrated Plex Client in MrMC is nice, but not as extensive as the PlexKodiConnect addon

If you have a capable TV that already has Amazon and Netflix apps with 4K HDR and DolbyVision capability,
AND you use LiveTV/PVR
I would recommend the Minix U9 over the Apple TV 4K.
Another side benefit is bitstream TrueHD and DTS-HD support with the Minix U9,
but LPCM should result in the same audio quality, though some receivers or soundbars don't support that.
