Broadcom still sucks. 50% of the time i boot my mbp in Arch the wireless interface just straight doesnt load even though the drivers are loaded and it is recognized with lspci

Some Atheros are not only reliable but ubercool. They support a gazillion options, including promiscuous mode, power saving, higher power transmission, etc.

In fact, Alfa Atheros antennas are the preferred option of those doing pentesting. Besides, I have great experiences with some models connecting to super low SNR networks where Broadcom would never ever connect.
