It is fairly OK in terms of the compatibility across Apple products - as always for the ecosystem. However, the way it works is totally poor - when the apps is closed (either by user or somehow killed by iOS) the airplay connection drops. In opposite, content played by chromecast seems to sustain individually, regardless of the apps status.
Even I am using iPhone and have an Apple computer at home, a chromecast hardware is installed and more frequently used than Airplay.
Do anyone else experience similar as me?
Not a comparison. The equivalent to chromecast is the remote control to apple tv. Airplay is just a way to cast whatever is playing to a different screen whereas chromecast is a remote control to tell the target device to play what you want (all decoding and processing are done on the target device)
