AX has a theoretical single stream speed of ~2.4 Gbps but it is almost impossible to get this speed. Limitations include distance, obstacles, your modem, your devices and contention with other networks. My Netgear a/n/ac/ax router has a max rate of ~2400 Mbps as shown by WiFi Explorer, but the actual speed that I get on my iPhone13 is in the 700-800 Mbps range.
The same will apply with 6E. You will never get the maximum speed. The video below tested 6E in a controlled environment and was only slightly faster than the values I see with AX - 906 Mbps for a single channel, ~2400 Mbps for all channels combined.
P.S. Without a summary people probably aren't going to watch a video. In this case it is particularly important since it is a non-English speaker.
