AXE16k since Dec 2022 + 3x XT12 wireless AiMesh. Stock firmware - latest. After getting it setup, its been absolutely rock solid. I did have to unlearn somethings. I was use to have scheduled reboot twice a week, this seems to confuse the dual-wan setup > switched off rebooting and its been rock solid. WiFi wise, no complaints and aimesh has been really good. Internet connection. 1Gbps and now 3Gbps up/down. No issues with the AXE16k itself or XT12s linked to it. My only issue is firmware. This router is so overkill if your not using Merlin, going to attempt Merlin again as on stock firmware there is 1.3GB or RAM sitting idle. Just remember, for 2Gbps+ links you will need to keep a number of options/services disabled but at this point it makes little difference. I disabled QOS/aiprotect/URL filtering/etc. For my WAN setup, I always clone the MAC of the router from the ISP (Virgin media modem trick I stick to), DHCP I set to continuous, I set WiFi 6e band to 160hz only, seemed to make rest of the WiFi setup more stable plus, 6e is next to useless anyway. If you got have 1Gbps+ link then for me, its the best off-the-shelf option - add in Merlin and its pretty damn good. I looked really hard at building a pfsense based setup but I settled for Asus as aimesh setup is very good for my setup.
