No gigabit port.

Poo. My current ISP (Cox) does offer 130Mbps. But for $20 this seems like a great replacement for my TP-Link that I put OpenWRT on.

Slightly more then 100 Mbit/s Downlink. But this also makes the 300 Mbit/s for Wlan useless. So maybe for some small stuff it is usable. But then again, it is not very cheap either.

There are many places (outside US) where you can get 200MBit for $10 or so.

1 gigabit symmetric for €20/mo here in Lithuania. Assuming you like cold winters :-)

Back on topic, what hardware are people with these sort of speeds running? It seems most consumer routers usually top out around 500mbit for NATing. I’m currnetly using a Mikrotik Hex with RouterOS, but prefer OpenWRT/LEDE.

I have an older one of these, and you can get full root on them. They are basically stock IIRC, if they aren't they can at least run stock openwrt. By default they have a simplified second web interface, with an "advanced" button that loads the openwrt luci web interface.
