I've had the entirely opposite experience here. Miracast just works for me. I have the Netgear receiver and I've used it with several different phones - Samsung, HTC, and LG. In fact, I know your chart is wrong because my LG Nexus 4 works fine with it. Meanwhile Chromecast is a joke. It doesn't work at work because our employee network requires a username and password and our guest network requires a click through agreement. It doesn't work at the hotels I stay at because again, they have a click through agreement. It works about half the time on personal WiFI APs where the person wasn't security conscience enough to turn on client isolation. The thing is nearly useless for me. Miracast uses WiFi Direct so works trouble free and lag free. Chromecast is some bizarre crappy second computer that has to connect to the network, but has very little capability to actually connect in the real world.
