Those two routers are more then you will ever need, take your pick, Im partial to TP link but never looked into that class of routers.
"fairly large house" can mean a million different things to people.
Is fairly large 3000 sq ft? 4000 Sq Ft? 5000 sq ft?
If your in the 4000 sq ft range you MAY want to start thinking "mesh" but avoid if not needed.
If your in the 3000 range -
These are worth a look for sure-
NETGEAR AC2100/1900 classhttps://www.techradar.com/reviews/asus-rt-ac86u
and other offerings from TP link.
I have been using a TP Link AC 1700 C7 V2
for years now in my 3000 sq ft home with ZERO and I mean ZERO issues. (the new AC1700 is not the same, with TPLINK you need to pay attention to the designations "C" "A" "D" as an example)
Im just guessing that I must have 20 devices on the thing, from cell phones, to 4 or 5 Roku players, 4 security cameras, 2 desktops, 2 laptops, 2 tablets, Channel Master OTA, Ooma phone service and I am sure a few more that I can not recall right now, on top of that my wifes VPN work router is plugged into the back of the TP-Link router with a NETGEAR power line extender. *L*
Our system is rock solid, never ever needs a reset, never have a range issue.
As far as the AX routers do NOT buy a router just because one router has AX and one is only AC. AX will work with NOTHING in your home at this time and if, if, the day ever comes that the manufacturers ever start shipping consumer products with AX radios in them, your router will already be outdated and due for replacement.
