I tested all modems for about two and a half hour and did some measurement.
I'm living in Germany, Baden Württemberg and for me the two ...ALK2 work best.
XXALK2 has a slightly better reception, but AEALK2 is better at WLAN conncectivity (faster) and finding internet connection at poor reception.
Interestingly the original firmware (T-Mobile) is the worst from all the listed ones, by far!
The internet speed in all networks (3G, H+...) is half (!) as fast compared to the ...ALK2 ones
I attached the exel chart I did for the test. It's German, but I hope you'll get what it means, otherwise I'll translate it.
