Netgear R7000 [1] with AdvancedTomato [2], which is Tomato but with a pretty UI. It runs DNS, nginx as a reverse proxy, SSH gateway and some other bits & pieces with minimal fuss. Pretty sure I've never had to reboot it outside of testing configuration changes. I even managed to upgrade to a significantly newer firmware version without blowing away the NVRAM/other settings and having to redo everything from near scratch as is IME so common with custom router FW builds (note: YMMV).

It has USB 3, GigE, wireless speed has been fine etc... certainly one of the best home tech purchases I've made in the last couple years.
