If you don’t want to flash the firmware or play around with the config files, I would go with the Huawei ones. If you want to do flashing and custom configs you should get the “tools” before you pick the dongle, otherwise, you will set yourself up for a big nightmare. Make sure you check the frequency bands in your area AND provider before you make a decision.
If you want to run a bigger operation, I would recommend some basic tools like a signal tester. That is the only way to make a decision based on some data. Also stay away from ZTE sticks if you don’t want to babysit the dongles (that won’t apply to all models but in this case, I would go better safe then sorry, especially for smaller operations).
You can put a lot of money into that research depending on what kind of information you want. We used one of the Siretta models when we started out but made our own tools in the journey that fits better to our specifications, especially if you want to check more then just signal quality. We also do a lot of domain-specific tests before deploying new apartments, since in the prime time everything can go to shit really fast if you don’t probe out the apartments upfront.
