Any recommendations? Just that I have in my own home 3 RT-AC68Us set up in wired Mesh and it has been nothing but stable and beautiful.Why you're looking at bunch of home routers then? I would get better looking APs with PoE instead. You have plans to replace the switch anyway.
I tried Unifi before and it was just not a great experience.
I just want the most STABLE connection / system possible (highest priority for me).
