The big advantage the WeTek Core has over most other Kodi Android devices, is it is a Google Certified Widewine Level 1.
That means you get full 1080p HD protected video streams from Netflix, HBO, Amazon, etc.
All these other Kodi Android Devices you see flooding the market, apart from FireTV's, Google Nexus and the nVIDIA Shield. Will only give you a max resolution of 720x480p video streaming content, this includes the MINIX AMLogic ones. This 1080p HD is a big deal for the WeTek Core, and a first for an AMLogic device. The bonus is you also get nice silky smooth HD Netflix video playback with 23.976fps video output.
OpenELEC is the other one. WeTek are an OpenELEC sponsor. It very easy to boot into OpenELEC. Flash a microSDHC card and plug it in and power up. And its pretty much a bug free version as you would expect.
What I'm reading over in this link for getting OpenELEC on the MINIX, looks much more complicated. You may even need to reflash the internal NAND and wipe the Android OS:

If what I read is correct both these devices have a WiFi Broadcom AP6330 chip. It is possible the Core has 802.11ac as well. I will check with WeTek. Regardless the MINIX implementation will have better WiFi reception sensitivity due to the external antenna.
