This. I've got a TPLink Repeater (RE450) and a Netgear R7800 router, both are running LEDE and have given me a slew of great features out of the box, and many more that can be installed after the fact using the packaging system.

There's also a third router, an old TP-Link 1043ND running as a wireless bridge to connect devices in my AV setup, once again running LEDE.
