I remember returning the Nvidia ShieldTV because of frame stutter. The match frame rate didn’t exist or work for me. There is only one device on the market that does this without flaws, AppleTV.

No other functionality matters for me if the picture quality sucks because of stutters. It’s a horrible viewing experience for me. I tried multiple devices before AppleTV and they all had problems with that one way or another and I eventually landed in AppleTV being the superior streaming device.
