Some of you know I was an H6 Pro owner until one week ago, when a WiFi Problem convinced me to return it to Amazon after one month of usage. At the same time i decided to buy a Nvidia shield TV, 2017 version with 16 GB Rom and 3GB Ram. I used it for five days, not so much but enough to find clear differences between the two products and appreciate minuses and pluses for both the solution (yes, there are things that i think are better on H6 Pro). Hardware: Connections: Zidoo H6 Pro has more connection ports then Nvidia Shield. The Nvidia Shield has 2x USB 3.0 ports, one HDMI and nothing more. Zidoo H6 Pro 1x USB 3.0 and 2x USB 2.0. H6 Pro has also a microSD card reader, AV out, Optical Audio and HDMI obviously. Wireless: Both claim Wi-Fi 802.11ac (2,4 / 5 GHz) and Bluetooth 4.1. about WiFi i cannot ensure Zidoo H6 Pro is like that, cause WiFi was faulty on my unit. CPU & GPU: It's an easy win for Nvidia Shield that mounts a NVIDIA Tegra X1 ( 4 core cortex-A53 + 4 core cortex-A57) with a 256 core GPU Maxwell. ZidooH6 Pro SoC Allwinner H6 has half the cores (4 core Cortex-A53), but i hasn't to manage cloud gaming. whatever the best performances of Tegra are good even for playback functions (i.e. Plex Server, not only player). ROM & RAM: both TV boxes have 16GB Rom upgradable via USB (or via microSD in the case of H6 Pro); RAM is 3GB for Shield TV and 2GB for H6 PRO. I have to admit that 2GB is more then enough for the Zidoo Box, that has no cloud gaming to manage, and I have never experienced slowdown in playback with Kodi, Netflix or internal player after a proper setup of the Zidoo box. Appearance: It's matter of tastes and the two tv boxes are pretty different in shapes and colours. I think both of them are beautiful in a different manner. so let's say they're even Remote control: both Shield TV and H6 Pro comes with a remote control using bluetooth and IR. i find Zidoo remote more reliable, it never disconnected from the box, while the Shield remote disconnects every now and then. It means: "use another way to go to settings and pair again the shield remote"; that's really annoying. On the other hand the shield remote as much more functions, less buttonsand a touch sensitive surface to slide volume up and down an to control the play and pause functions of the playback (no matter the app). The Shield remote has a builtin microphone to command the TV box through the voice. H6 Pro remote is pure plastic but solid; Shield remote is plastic and aluminium: both look good, shield remote has more premium look. Finally Shield Remote can control the power on and power off of both my TV and soundbar while i put to sleep the Shield TV, as well as change directly the volume of the soundbar. Zidoo claims CEC control but i wasn't able to find the option, whatever the function was not so deep as the one offered by Nvidia: Since I have Shield i am using one remote; with Zidoo i was using Three. in few words Zidoo controller is more reliable, but Shield controller has more features and looks better. Nvidia wins. Software: User Interface: Nvidia Shield is based on android 7.0, delivered through the Leanback UI, the default Android TV user interface. Zidoo is pure android 7.0, customized, and delivered through the Zidoo Taurus UI. Well, i don't like them, not Leanback not Zidoo Taurus: they are easy to navigate with remote control but their lack of customization is irritating! H6 Pro gives the possibility to switch to a third party UI app, Nvidia Shield not cause there is no option to force the home to another app. And Leanback UI is even more annoying cause if a non android TV app is installed i don't see it in the home screen (there is no app drawer). To see non android TV app is needed an application named "Sideload launcher". Leanback UI looks more beautiful because of the resolutions of the objects, but Zidoo wins the UI battle, because gives choice to the user to change the default UI application. Playback: Zidoo has a good internal player, it's reliable, well done and rich in functions. The contents navigation is ugly but effective. Playback on third party apps, like Kodi, is not always good like the internal player, but fine tuning the box and the apps helps to solve the problems partially or totally. Nvidia Shield has no internal player, no file manager and is dificult to find a file manager optimized for android TV. The good thing is that Third Party apps works very, very and let mesay VERY well. I admit it was more simple to install kodi addons on Zidoo then on Nvidia Shield, but in the end Kodi rocks on Shield TV. Plus Shield TV works well with plex, enabling not only the plex player, but also the server side of Plex; it means plex transcode and send video and music to other devices through the internet. Is not powerful like a dedicate server, but it works. Playback on Nvidia is much better and works fine out of the box, but there is no native player and no native file manager. Netflix[updated. Thanks to @leonkoum ]: I've to dedicate a special paragraph to the king of online streaming, even if short. Everybody having a Zidoo H6 Pro knows it implements DRM that enable FHD Netflix Playback. Nvidia Shield let Netflix works to the max resolution possible (4k) out of the box. It's a win for the Shield TV. on screen Keyboard: ok this would look a strange comparison for someone, but i think is important to know that on Nvidia Shield there is a special on screen keyboard named "leanback keyboard" after the UI name. Well, when i started my Shield TV i had odd options in front of me: Russian/ Czeck keyboard, chinese and other far east languages. I didn't find Italian (my language) or english. I unistalled or disabled all the other options, found "leanback italian keyboard" on the play store, but it didn't work. Zidoo with his android 7 non TV Operating System, gave me the possibility to use the keyboards i needed. So, few Keyboard options on Nvidia Shield, much more on Zidoo H6 pro. Firmware: Much more stable on Nvidia Shield. This is all for now, when i have time to try and write something else i'll update the comparison. If you have some special question, please let me know. Even if i don't have H6 Pro anymore, with your help we can make this comparison better!
