Dumb take.
There is certainly a benefit to 6e.
- Real-world speeds never reach published speeds because of the nature of WiFi protocol + RF environment.
- The highest published speeds typically require clients with 3 or 4x radios. iOS devices don't have that, and nor do any current macs.
- Available bandwidth drops as neighbors upgrade to devices that use new spectrum. 6E devices have access to new frequency bands.
- In some markets (not the US) >1Gbps home connections are affordable
That has been my experience. For me, whatever the highest advertised speed is, I cut that in half as a theoretical best case scenario that one 'might' get.
