Current Best WiFi USB adapter?

[Tritium]

I've done some research and have a general idea on USB adapters that are compatible with Kali/NetHunter.
Searching yielded a few similar thread, but none matching exactly.

My minimum on the adapter is:

• a decent *actual* power(mW) rating.
• Wireless N compatibility on 2.4GHz (5GHz is a plus but not necessary).
• External/Removable Antenna.
• a fully supported chipset.

I've narrowed down my choices to 3 adapters. (In order of what looks to me to be best to worst)

1. TP-LINK_TL-WN722N (Atheros AR9271)
2. ALFA AWUS036NH (Ralink RT3070)
3. ALFA AWUS036NHA (Atheros AR9271) - Noted that the "FCC test results, this adapter is ~5 times weaker than typical Wi-Fi adapters"

Also interested in the Signal King 950WN that uses the Ralink 3070 chipset.
It seems to have really good reviews.
And would like to know more about the Alfa AWUS051NH v2 (dual band).

Out of those adapters and other adapters that I may not be aware of, which is the most powerful and better of the supported USB Wireless Adapters or Kali and NetHunter?

The compatibility is based on chipset and should have any of the following chipsets (802.11N):
Atheros AR9271
Ralink RT3070
Ralink RT3572

I've also discovered that there are some Alfa adapters that are claiming 5,000mW power from a single USB connection.
It appears that is impossible since typical USB 2.0 ports put out 5V at 500mA max, which means the absolute maximum output of a single usb powered adapter is limited 2,500mW. (5V*500mA=2,500W - P=V*I)
That is assuming perfect conditions which would likely never exist in actual practice.
