I use a Linksys Velop system at home that replaced my two Airport Extremes. With my airport network, my phone would hold onto the connection to the one I first connected to, despite standing 10 feet from the other one. With mesh, at least it appears to jump from one to the next fairly quickly.
The Velop mesh units each have two Ethernet ports on them and I have them hard wired into my switch. They can either run with a wired, or wireless backhaul.
