It depends on your understanding of better. Better for most home users is set it with few clicks on a phone app and forget it. Your $300-400 router won't be 6-8 times better in Wi-Fi compared to $50 router and one day you'll find your teenager bypassing $200 worth of "features" with few clicks.
bandwidth speed, connectivity issues, filtering, blocking malware/virus/etc, router scheduling (for now), Ethernet ports (like 4), Nat(?), Vlan tagging
Don’t think I care about QoS, back up (like Apple Time Machine), media server, is an IPv4/6 good?
It’s nice to have a guest network, an app
Not sure what I need for the reliability and speed…
like mumio or whatever that is… I think WPA3 is best for security. For reliability I just really care about a one room, coincidentally I’m in the room with my router and they are in the other room, or they are connected by Ethernet.
I have two smart lights, then about like 11 devices (5 laptops (all (or can be) are connected to Ethernet, either from the router or a switch), 5 phones (via WiFi), 2 tablets, 1 desktop computer(Ethernet)), and rarely an Apple TV (Ethernet), randomly a Nintendo switch. There is occasionally other devices but those are the normal ones.
Not sure the capabilities of the phones if they support WiFi 6 or not.
