HTPC makes a very poor streamer in comparison to the dedicated streaming boxes. Netflix and Hulu are the only two services that have dedicated apps and are Windows 10 only. Audio other then PCM stereo aren't supported by any of the browser based services. 4K on a limited bases maybe on some services in certain browsers. AppleTV comes the closest to supporting the most available from the streaming apps (Atmos/HDR/DV/4K). The 4 top streaming boxes are the Roku, FireTV, ATV and Shield and highly recommended if you want the best for streaming. HTPC is best at playing ripped content through a processor like MadVR.
