Have you upgraded to WiFi 6 - 802.11.ax?

Am about to move houses and new place will have 1000/1000 speeds. Wondering if I should get a Wifi 6 router or not, is it worth the upgrade? Can Wifi 5 and 6 equipment be combined? Or will it then all be 'downgraded' to Wifi 5?

Usecase: At home - with 8 or so devices.

Anyway, let me know your experiences with WiFi 6 and wether I should aim to get it.
