Here is a summary of the leading contenders for best device in 2024:
S905X4-J Devices
Supports AV1, Dolby Vision including FEL, and 3D on CoreELEC -ng. However, they cannot decode 24fps VC-1 content. CoreELEC cannot be installed on the emmc. It must be run off an external device. However, the data partition can be stored on the emmc with HS400 enabled.
- Homatics Box R 4k Plus - certified device that supports Netflix and probably has the best support because it is made by SEI. It had no sdcard slot meaning than COREelec must occupy a USB port. The lack of an IR receiver makes it impossible to wake from sleep. Runs Android TV 12 with Android 14 rumored for the future.
- DuneHD Homatics Box R 4k Plus/Nokia 8010/RockTek G2 rebadged Homatics Box R 4k Plus, but with worse software support. Some of the varieties have an micro-sd slot or IR recceiver. Runs Android TV 12.
- Ugoos x4q Extra is not certified and does not support Netflix/Amazon/Hulu, etc, but has more internal storage space.
S922X-J Devices
Supports Dolby Vision including FEL and 3D on CoreELEC -ng. They can decode 24fps VC-1 content using a software decoding. Somewhat faster than S905X4-J devices, but more expensive and lack hardware support for AV1. CoreELEC can be installed on the emmc and HS400 enabled which greatly reduces boot time and speeds up the which greatly reduces boot time and speeds up the interface making it feel significantly faster than the S905X4.
- Ugoos AM6b+ - actually available for purchase. Does not support Netflix/Amazon/Hulu. Runs Android 9.
- Minx U22XJ Max - no longer for sale
- Amazon Fire TV 2nd gen Cube need to buy a sealed unit on ebay and unlock the bootloader. It has full DRM (Netflix, Widevine L1, Playready) support. However, it lacks a built-in Ethernet port and only has one Micro-USB 2.0 port.
S928X-J Devices
Supports AV1 and Dolby vision but no FEL support. Does not support 3D. Can run the GUI at native 4K.
- Choose from Ugoos AM8 (Pro), Tencent Aurora 5 X, X96 X10 Pro [the non-pro version does not support Dolby Vision], or Ugoos SK-1 based on your personal preferences.
Conclusion
The best device depends on whether you want one box for Certified Android and CoreELEC or the best dedicated CoreELEC box and a separate Android box.
If you want a box that can run premium Android applications and CoreELEC, then the best overall device is the Homatics Box R 4k Plus with its support for Dolby Vision including FEL and AV1 with a certified Android TV box. However, CoreELEC will run slower and may not be able to decode some older blu-ray movies.
If you want the best media box to only run CoreELEC, then the Ugoos AM6b+ is the best box with it’s faster processor and the ability to install COREelec to the emmc with HS400, but it runs an older version of Android and sacrifices support for certified apps including Netflix and AV1. However, only the Ugoos AM6b+ can fully replace a disc-based player.
