I have tried both Atheros AR9280 AR5BHB92 and Broadcom BCM94322HM8L (504664-001). Based on my experiences (5GHz band) I would recommend BCM94322HM8L.
Atheros AR9280 in addition to "unknown locale: 69" errors in console (unpatched EEPROM), it is very slow during boot and may fail to connect initially. I have to Toggle WiFi On/Off to get it to connect very first time (it seems ok on 2.4GHz). After this it seems to work ok until next reboot. Broadcom works flawlessly. It is also 1/2 price vs. Atheros AR9280 and it is available locally.
I have both 4540s and 4440s. I would recommend 4540s over 4440s as it seem to have better (quiet) DVD drive and web cam works in Photo Booth and Face Time. Both are using the same web cam hardware, but 4440s requires 3rd party App to "wake" web cam for Apple Apps. Otherwise, both are good, stable machines. I am not sure about why web cam on 4440s acts differently, but it might be because of I changed web cam settings to HD in Windows Web Cam App. Maybe it had some residual effect. But the video quality seems way better on 4440s. May be I found a way to fix the video quality issue, but the price to pay is the need to "wake" camera before Apple app could use it. The discrepancy is in version of the web cam: 4540s has version: 57.70 and 4440s has version: 57.51
