I just upgraded to a WiFi 6E router. Both my phone and my laptop support 6E.

Speeds are great, until you leave the living room (where the router is). Go up to my bedroom, and 6E won’t even connect. So it’s fast, but 6Hz has trouble going through walls.

Most of the other devices in the house are in 5GHz and that’s still super fast and able to reach basically everywhere.
