I've owned the original Steam link hardware, RPI 4, Chromecast w/ Google TV, and now the Google TV Streamer. Up until now, the best steam link experience was always with the original hardware, but the Google TV Streamer has ended that reign.

Streaming PC Host runs Linux and is hard wired to the router, but my steam link hardware, etc are 5Ghz WiFi streaming 1080P.

Original Steam link hardware:
- < 1ms input
- < 1 ms ping
- ~22 - 29ms Display (wifi controller mode)

RPI 4 hardware:
- < 1ms input
- < 1 ms ping
- ~26 - 32ms Display (wifi controller mode)

Chromecast w/ Google TV hardware:
- < 1ms input
- < 1 ms ping
- ~35 - 48ms Display (BLE controller mode)

Google TV Streamer hardware:
- < 1ms input
- < 1 ms ping
- ~13 - 16ms Display (BLE controller mode)
