I have 68 things running on my wifi.
I just recently upgraded from ASUS Wifi 6 mesh to TP Link Deco AXE5300 mesh with wifi 6E.
I don’t have any 6E devices but the back haul uses it. These things are a lot faster then the ASUS units were. And the range is amazing as well Got a 3 pack of them at Costco for $279. (The 5300 is a special 3 pack for Costco but the normal model number is 5400)
I am very happy with them. This is wireless speed from about 20 feet from the router.
