My Airport Extreme finally died a few weeks ago and I replaced it with an OnHub (the TP-Link one). Couldn't be happier -- my Wifi range extends well beyond the perimeter of my house, speeds (appear) to be faster with less connection issues _and_, I can monitor router activity and other stuff directly from their App (though that is the one area it could use a few more features).

Google is definitely winning some points in the "simple and works" category. Pricey but worth it, IMHO.
