Better (10-15% faster throughput in my setup, but> 15 euros and bulky because of the two antennas) was only the TP-Link WN822N v2.0 (Atheros chip)
This whole nano sticks and everything under 300Mbit N-Fi, all were not useful, the function presumably only good line of sight between adapter and AP but quickly show their limits when a 30cm massive wall in the way.
