Orbi AX has WPA3 though not in mixed mode with WPA2. NG found a problem early on in development and had to separate WPA3 from using mixed modes wtih WPA2.
Orbi AX is pretty good. Were getting thru some FW issues seen from last year and seems to be heading in a better direction.
Review the various forum threads here if your considering a Orbi AX system:
