Absolutely the best is NVidia Shield. It's both the most powerful, and running Android TV designed for normal use with remotes.

A cheaper analogue is Mi Box S

Qualify "Best" ...

People keep banging on about Nvidia Shields being the best but quite frankly those people are just following the herd.

Yes, it's powerful and fast but that doesn't necessarily equate to best.

• There are multiple reports of poor 4K image quality on the Shield, just look at the Nvidia forums.
• Report of poor colour rendering with HW acceleration turned on.
• Poor 1080P > 4K upscaling
• Broken unreliable/deinterlacing
• No Dolby Audio licence
• Not 4K HDR YouTube or 4K HDR Google Play movies capable

I'm not bashing the Shield, I'm sure it has redeeming features but Let's not be sheep and copy/paste "Nvidia Sheild" every time anyone asks what the best Android box is.

For 4K HDR10 Hi-Res audio use (for example) the Minix U-9H is much better.

4k firestick

I like the Dreamlink t 2 or the formular which is the same. Price is great but the dreaamlink t23 records better than nvidia in my opinion but if u play video games then the NVidia is the way to go but if u want just iptv and apk's dreamlink is best choice then u can also go to the firestick 4k then jailbreak(easy to do)

I like the T95Q
