So I played a bit with AirLink... I set it to dynamic bitrate, with the max up to 200 Mbps, and it seemed to work pretty well. I'm not sure if this changed with v31, but I noticed that the image quality at the edges of view seemed to be more aggressively degraded. Previously I only ever noticed it in a thin border along the rims of the lenses, but now I can see it outside of a rectangular area at the centre. It's not specific to AirLink, because I also saw it when I switched back to tethered Link. Maybe it was just the game I was playing--I was in the Lone Echo in the Processing Line area, and there is a diamond pattern in the glass walls that makes the quality drop-off very obvious. I had turned off TAA last time I played this game, so that may have also contributed to me noticing it.
Edit: This was not a Link issue, but a setting in Lone Echo. When I turned off Multi-Resolution Shading, the image quality was back to normal.
Anyway, my only complaint about AirLink versus tethered Link is that I can see some loss of image quality with the lower encoder bitrate. There's a spot in my Home environment where I can always see colour banding if I use a bitrate lower than 350. With AirLink at 200, I can see it in the area circled (although it doesn't show in the picture). Other than that though, I didn't feel any difference going back and forth between wireless versus wired.
Main thing I'm noticing now is that there is not as much difference between Link and Air Link. Maybe thanks to my rtx3090 gpu but I can now run Air Link at 200mbps Fixed Bitrate and this looks/works very well for me with 90Hz refresh rate, 1.2x slider (4480x2256) and 1.20xSS, ASW = off, with OTT.
In order to get the same result with Link I need to use at least 350mbps bitrate. I can move this to 500mbps and this further improves things a bit. Overall, I still prefer to be wireless with Air Link.
I feel that both Link and AL have lost some performance/clarity since v29. With v29 I was easily able to run 120Hz refresh rate at 1.4x res slider and 1.2xSS. Now, I seem to get some stutters which are completely fixed by dropping the refresh rate down to 90Hz. Currently, Virtual Desktop does a much better job at 120Hz but I prefer Air Link because I like its colours better. VD colours always look washed out to me and adding colour vibrance gives everything too much of a reddish tint. Plus, not all my apps (esp. VivePort apps) are compatible with VD and/or some controller actions are a bit off.
