Got mine hooked up this afternoon. So far, it has been fantastic. Very happy I replaced my AC88u.
Testing with my Samsung S20 Plus, the Wi-Fi 6 connection is definitely an improvement.
I have a symmetrical 1 Gbps Fiber line and testing with Ookla there is a difference on Wi-Fi.
Attached are some speed test comparisons using the same test server. These two are my AC88u and my S20 could barely crack 400.

These are the AX86u and are from different points around my apartment.

For reference, my Desktop, hardwire get around 950 both ways.
