banjobang 2.4 GHz Is shorter in range and subject to obstacle too. 868 - 900 is less subject to obstacle (i.e. trees, Buildings, etc.). Problem with 868 - 900 of you travel, some countries are 900 MHz legal (i.e. usa) other 868 (i.e. Europe). so if you travel often, Better 2.4GHz but of you Need consistent links Better 868 or 900.
