I've just tried a TP Link Tri band AXE 5400 6E router with my Quest 3, the latency in Virtual Desktop is about the same as my ISP issued Sky 5GHz router. That was with AV1 (10 bit)/150Mbps/Godlike. I think it was no faster because there's no congestion where i am on the 5GHz band, none of the neighbours are using 5GHz yet and I only have my Quest 3 on it. It's going back to Amazon.
You should really try H.264 at 400mbps on both Airlink and VD and see what your latency is like. And see do you prefer it over AV1.
EDIT: I think you should also try a lower bitrate when using AV1, like 175 or 150 even. See do you notice a difference. 200mbps might be pushing the limits of the decoder which is why there might not be much difference between the new router and the sky one.
