This is probably the wrong forum to ask about comparison to a media player not sold by Futeko.....
It really depends on what you want it to do and if you are happy with the high quality video output from your Q10?
Summary of Shield issues thanks to the Kodi forum:
NVIDIA Shield (Nougat OS):
No OS/Apps - auto colorspace switching/conversion for correct color outputs for seamless SDR / 4K HDR usage.
Relatively poor 1080p > 4K hardware upscaled picture quality vs the competition and what a 4K TV can output using it's superior upscaling hardware.
Alpha (meaning a bit buggy) Kodi Leia 18.x (& soon MrMC) can work around this poor upscaling with auto 4K <<-->>1080p resolution switching, however then....
Colorspace 4K HDR >> SDR will still be a problem and what about picture upscaling for other non Kodi Apps ?
Broken unreliable/deinterlacing for Kodi Krypton PVR Addons. Use Alpha versions of Kodi Leia 18.x instead.
For Apps usage - only Kodi, MrMC, Plex and Emby can auto refresh switch for smooth video playback.
Issues with 4K HDR & HD Audio passthrough if using Ethernet, click HERE for details.
Be aware the Shield has no Dolby Audio licence, so Apos that stream 5.1 DD+ Audio like Netflix and Amazon Video needs a HDMI connected DD+ audio receiver. Otherwise expect 2.0 audio only from such Apps.
No 4K HDR YouTube. 4K SDR only.
Android TV Oreo OS - Shield Colorspace testing conducted over HERE (click) by @wesk05
HDR to SDR or BT.2020 to BT.709 conversions not yet checked.
Oreo - Colorspace issues still being reported when used with a variety of 4K HDR displays, see HERE (click) for details.
Thanks for the in depth reply.
I have read quite a bit on the topic and decided to go for the Q10 pro again. I know the product quite well now and its shortcomings.
I guess the main thing that was tempting me to the dark side was the 4k netflix, potential gaming and larger user base.
But in saying that, my TV has built in 4k netflix, i dont think i have turned on my gaming console for 3years and this forum has been helpful.
Plus was $150 /$250 cheaper depending on the model you go for.
So now to send back the defective Q10 and wait for the new one to arrive.
Cheers
