Personally I’ve had really good luck with the Netgear Nighthawk R7000 and R7800 models. They are supported by openWRT as well if you are into that. An issue might be that they are “only” WiFi 5 units. Some of the newer models in the Nighthawk series might be just as good, but i don’t have personal experience with those…
