I'm asking out of curiosity and in the hope of gaining insights for future improvements.
I currently use an Asus AX88U Wi‑Fi 6 router that covers my 200 m² home well. I might move to a larger house next year, and I'm considering adding another Asus router (not necessarily the same model) to create a mesh system.
Happy to hear comments from owners of Netgear/Ubiquiti/TP-link or other brands. What do you like and don't like about the current system?
I run grandstream networks gear, bit more cheapies friendly than unifi system. The gwn7062 router in garage with its own wifi , includes a controller built in. That connects to a poe switch (tp-link, less than $100) which I connect another access point to at other end of house on other floor (gwn7660LR). I get seamless roaming through the two floors with all the devices and setup was easy. You can use the nonLR version which is even cheaper if you can ceiling mount but with the layout of this house, I didn't have convenient access to cable runs for that so used the LR version which is just sitting on a shelf.
