ASUS RT_AX88U, RT-AX89X or cheaper option AX92U

cgaie

Guys I need your help to decide which router to get RT_AX88U, RT-AX89X or AX92U ?

I have at the moment an AX86U and I want to get another ASUS router to use as a node ( I need 8 LAN ports to connect wired devices)

This router is going to be in my office room connected to the main router wirelessly not wired and I will be using the 8 ports on it to connect wired devices

The most important thing for me in the new router (the node) is a solid wifi connection to the main router and use the 8 LAN ports on the node router or if I go for the AX92U 4 LAN ports

Which router should I go for AX88U, AX92U or the AX89X considering my configuration? I'm not sure if the top of the range router needs to be the main router and not the node, or it doesn't matter which one to have as the node

Thanks
